[Hunter wears back] Xueba, don't run!

"The use of a transistor as a switch refers to what and what state is its working state?"

"Saturation and Cutoff!"

"According to the trigger method, what are the three types of triggers?"

"Level trigger, pulse trigger and edge trigger!"

The chivalrous man who was acting as a teacher smiled slightly, "Bingo, all 20 questions are correct, next is Lin Lin."

Zheng Chang, a single-celled creature who answered all the questions right next to him, shouted, his flamboyant expression was unbearable, but now I don’t have time to pay attention to his provocation, because the knight-errant smiles and keeps that expression for a moment. Instantly looked at me.

joke!Am I the kind of person who can remain indifferent when others are flaunting provocations in my ears?

of course!

No, no, this is actually not the most important thing. The most important thing is that my mother called yesterday to say that she got a ticket for a family trip to XXX beach for a week in the online lottery, and said that if I still fail at the end of the semester, I won’t have it It's all over.

This time I didn't complain about my mother always believing the fake lottery information on the Internet, because the knight classmate went to hack other people's websites as soon as she knew about it...

Then found out it was true.

At that time, our reaction was almost an expression of being struck by lightning, right?

Qiu Yun said that even if it was hit, it was still scorched on the outside and scorched on the inside.

So the second thing the knights did was to make a pre-examination assault training exercise table, from Ja (there must be an obstacle between these two letters) va to the operating system to the single-chip microcomputer to the digital circuit to... 20 test questions to test my review.

It's just why Zheng Chang took the initiative, this matter is complicated, let's make a long story short and skip it.

The knight picked out the information in his hand, his expression froze on a smile after experiencing doubts, contemplation and deliberation. "Ah, that's it."

It turned out to be the principle and application of radio frequency identification (RFID) that I hate the most.

"Then let's start. Each question must be answered within 10 seconds. If you can't do it, you will fail in the summer seaside battle."

"Hmm, let's get started... eh, why do I have to be Zheng Chang within 10 seconds..."

"Briefly describe the characteristics of RFID technology."

"Isn't it a fill-in-the-blank question!?" I flipped the table.

The knight began to count with a straight face: "1,2,3, [-], [-]..."

this person!Ma Ma bullied me!

"Ah, I answer, I answer! The first is the wireless reading and writing function of data, the second is the fast scanning function, the fourth... the miniaturization of the volume, the fourth is the variety of shapes, and the fifth... endurance, oh no, it is environmental resistance !” At that time, the teacher asked us to take notes while reading, but this teacher’s way of teaching has been criticized by us for a long time. No matter how fast we take notes and remember, it’s not as fast as she skips knowledge points as soon as she finishes reading. "...The seventh is the large data memory capacity, and the eighth is the system security!"

"next question."

Ah... Xia Ke's speed of changing questions is comparable to that of the teacher.

"A brief description of the basic principles of RFID."

These two questions were really a headache when I first learned this course, but relying on my years of experience in memorizing classical Chinese, I can basically remember this kind of thing after reading it a few times.

"The reader sends a debugging signal through the antenna. When the electronic tag enters the reading and writing work area, the antenna generates an induced current through coupling to provide energy for the electronic tag. At this time, the tag decides whether to respond according to the information sent by the reader... "

"..."

The pleasant (not) time flies by, and it is time for the final exam in a blink of an eye.

Looking at the first big question and the second big question on the RFID test paper, I secretly glanced at the knight in front of me, and decided not to ask him whether he hacked the school system.

Anyway, this is also the result of my so many days of hard review. To ask this kind of question...is not confident in myself and distrusting knights.

Due to the renovation of the old dormitory, the end-of-semester period was very tight. The original exam week was shortened to three days. After three days, all our sophomores and juniors moved out of the dormitory.

The senior seniors moved out two days before our exams. At this time, the dormitory building was filled with the smell of sawdust from the demolished bed boards and the thick wall dust.

Four days later, the preliminaries of the Internet of Things Contest will be held in City C, not far from our school. The school decided to reserve a new dormitory building for the several teams participating in the competition. There will be a dedicated life teacher in charge of daily living, and each team will also be led by each team. team teacher.

This time, there are four groups that entered the preliminary competition through internal selection. Compared with the three groups that entered the national finals last year, the base number is much smaller, but the teachers agreed that this year's participating groups are of the highest level.

After the school selection, there will be the preliminaries at the municipal level, the semi-finals, the finals, and after that the national finals.Each group can use the same work to participate in the evaluation before the municipal final.If they pass the semi-finals, they need to produce another work in the final, otherwise they will be eliminated.And if you don't pass the semi-finals before then, you have to come up with another work for evaluation, if you still can't pass, you will be eliminated.Works that have appeared in the semi-finals cannot appear in the finals, otherwise they will be eliminated.

During the summer vacation, only the city-level preliminaries and semi-finals are held. These two competitions are put together, and all "uninnovative and unimaginative" works will be eliminated within a week. The final will wait until the National Day, and the national competition will have to wait until next year. month.

After listening to the competition rules explained by the teacher, I tugged on the sleeve of the knight and asked in a low voice: "When did you participate in the internal selection?" Isn't it possible to participate after signing up?

Qiqi rolled her eyes when she was sitting next to me, "I really don't want to talk about you, bomber."

Qiu Yun nodded seriously: "Little Angel Linlin, you should also pay attention to this kind of thing."

I:……? ? ? ?

The knight stroked the broken hair on my forehead, his smile remained unchanged.I looked around and found that no one noticed our small movements, and I couldn't help but breathe a sigh of relief.

"So when did you not tell me!"

Zheng Chang tapped my shoulder and said: "Although I signed up, the level of the works is uneven. There were 9 groups in the free group at the beginning, and each group has a teacher in charge. The role of the teacher is to guide the students Put forward suggestions for improvement on the works that come out, and the improved works will then participate in the school selection, and the selected... only the four groups of us present."

"It can also be said that no matter how much garbage is modified, it is still garbage, and good things can be seen at a glance." The knight stopped me who wanted to continue asking questions, and said with a smile, "The selection time is after we form a confirmed group. that Saturday."

"Hey, classmate Xia Ke, it's too much to talk about garbage..." Zheng Chang pouted and looked at Xia Ke in disapproval.

Xia Ke shrugged his shoulders, with an extremely relaxed smile on his face, "This is confidence in our team, isn't it good?"

"I can't say it's bad..."

Zheng Chang was deceived by the fox in this way.Knowing the nature of foxes well, I decided to remain silent.

The spider has been dormant for too long, and the sharp thorns on the legs will become an obstacle to progress if they are not soaked in blood.

I basically didn't listen to what the teacher said later. Zheng Chang, who was in the same group as me, was probably still struggling with the discomfort that the knight's words brought to him. He probably didn't listen to the teacher's words like me, but our group...

I took a look at the other teams around me, and I couldn't feel the aura of elites or academic masters. Maybe our team has a much higher chance of winning the ranking... right?Although it is said that people should not be judged by their appearance and sea water cannot be measured, but having both talent and appearance is the kingly way!

Afterwards, the teachers of each group led their members to the temporary residence.

The teacher in our group happened to be Mr. Wang who taught us the operating system. He was well-known among the students for his humorous lectures. Everyone kindly called him "Old Wang".

After Pharaoh led us to put our luggage, he called the five of us to have a short meeting.

The content of the meeting is that these four days can be freely arranged, and the school's library laboratory building can also be freely entered and exited. The only requirement is that the other three groups on the other three floors cannot be disturbed.The school generously allocated each group to each floor this time, and the five-person room was used as a single room.

I suspect that what Lao Wang told us is likely to be what the teacher in charge said before, making up for the shortcomings that I missed.

"Well... I hope that you guys will give full play to your talents in this competition, use what you have learned, not only for yourself, but also for the school, and use [-]% of your abilities to stimulate your unlimited potential. .”

At the end of the meeting, Zheng Chang breathed a sigh of relief, "Generally speaking, the main point of Lao Wang's speech is to play whatever you want in these four days. You have to work hard in the competition, and then it's gone."

"Well, that sums it up pretty well." The knight patted him on the shoulder, turned and walked into his bedroom.

Zheng Chang blinked, looked at the closed door of the knight, then at us who were about to go back to bed, and finally focused on me, blink, blink.

"...Don't look at me with such disgusting eyes, say what you want."

Zheng Chang sighed: "I heard that there is a very high mountain in a county not far from the school. It is said that the Buddha in the temple on the mountain is very spiritual..."

I squinted at him. I don't know whether this kid is pure-minded or too stupid. Sometimes he is very childish and full of sense of justice. Sometimes he drives an old driver improperly. Sometimes...

There is a feeling of deja vu.

I shook my head, shook this thought out of my mind, and said: "The team leader is a knight, and he must get his permission to do anything. In this case, you might as well find him."

"I just came to you because I didn't feel comfortable looking for him, Bomber!"

"Damn it, try calling the labor bomber again!"

"Sister, I was wrong, I want to go hiking, I want to go on a picnic!"

I really... can't get enough slaps, you damn kid!

In the end, when the anger subsided a lot, the hem of the clothes was held by him again and shook slightly.Suddenly there is a feeling of having a child.

Illusion?It must be an illusion!

I couldn't resist Zheng Chang, so I found the knight after dinner and talked about it.Xia Ke frowned and searched the Internet, and replied to me: "The weather has been different in the past few days. It is better not to go to such a far place to climb the mountain for the time being. The competition is about to be safe and the top priority is guaranteed."

At this time, Zheng Chang appeared out of nowhere, and said anxiously, "Tomorrow will be sunny! I read the weather forecast!"

Xia Ke rubbed his eyebrows, I'm sure he must have the same thoughts as I did before.

This child is really hard to take.

The chivalrous men who have not beaten Zheng Chang were extremely helpless, gathered a group of 5 people, and put forward the idea of ​​relaxing mountain climbing before the game. Qiqi said that it doesn't matter, I will go and she will go, Qiu Yun expressed the same opinion as Qiqi, and I can't say it now. "Actually, I don't want to go."

Everyone excitedly (in fact, Zheng Chang and Qiu Yun were more enthusiastic about this matter) started to pack their things, and Zheng Chang went to a small store outside the school to buy dry food and water.

This kid really thinks that he is going on an outing.

The next day, I explained the reason to the teacher, and the teacher approved it with an unteachable expression on his face. I think you guys are about to compete, but you still have the energy to climb the mountain. Could it be that this competition is about to give up... Finally, I told the teacher You must be back at school before ten o'clock in the evening.

After getting into the car, everyone breathed a sigh of relief.

"I thought Lao Wang would not agree."

Qiu Yun replied: "No, he is not the kind of person who can take care of these things. Let me tell you, this competition is not just a competition between students, there is also competition between teachers."

Qiqi looked at her in surprise, and said, "No way, shouldn't the students from the same school be more united and friendly?"

"Oh, Ma Qiqi, you are so naive. This time, the most promising group among our four groups is the group of the second major class of the Internet of Things major. We represent the first major class and successfully passed the school selection. Even if the teachers of the Internet of Things major must have knowledge of various subjects, Lao Wang is not the most outstanding group of teachers in the school, but the leader teacher of the second class is. He also broke into the school last year. The teacher who leads the team that gets the highest ranking in the final."

Qiu Yun gave us a knowing look, "So I don't need to say more about which group the school pays more attention to in this competition."

"Indeed," even Xia Ke couldn't help nodding, "The atmosphere in that group is completely different from our three groups."

I don't think there is any difference between that group and our atmosphere, and it's not an elite face...

"Because there is competition among teachers, Lao Wang doesn't like those who compete. He has never been involved in these, so he has never been able to be responsible for the leadership, but because there is no one else, and Lao Wang's strength is not bad, so young Let him lead the team every year, but every year is not the team that is valued."

"So Lao Wang is actually pretty miserable," Zheng Chang touched his chin and said, "How about we get first place this time to make him happy?"

Qiu Yun rolled his eyes at him, "Then you go back and seriously prepare for the competition now?"

"To be honest, I don't think there is any need to prepare at all."

"+1."

"+2."

I picked up a pack of biscuits nonchalantly, and gnawed on the milk. I didn’t have enough breakfast and I was too hungry. It was necessary to reduce the weight of my backpack before climbing the mountain.

"Anyway, there are knights." I said vaguely, and ate another biscuit.Xia Ke is a super big cheat, what can I do if I don’t make good use of it?

"Cough cough! Cough cough cough cough cough!!!"

The author has something to say:

I haven’t updated the article for a few days, and when I found that there were more than 20 comments, to be honest, I felt like I ate a whale (just kidding). Looking back, I found that this article has been written for half a year, and the blue goose has only written half of what I expected. ┑(￣Д￣)┍I don’t have much perseverance. I have always been motivated to write as long as someone reads it. At first, it was just a little brain hole, but it happened to be written down. It was just out of interest at first, but I found out... when someone replied and someone said a few points that they wanted to highlight when writing the article... Wow, I was so touched!

I still have 20 days to start school, unlike Linlin Youxueba who did not fail this time, I am a human being this summer vacation!born!No.!one!Second-rate!hang!division! ! ! ! ! !

Fortunately, the refurbishment of our dormitory building has delayed the start of school for a few days, so we have more time to play!Watch anime!Write!play games!I’m really hopeless too┑(￣Д￣)┍

Just kidding. The accelerator expires at the end of this month. I don’t plan to recharge the money. Although the [-]th anniversary of the foundation is over, and the pendant is about to be released, and I’m about to refresh the book, I decided to finish the Chinese Valentine’s Day with Master and start school in September! Ah!up!Then review qwq well and wish me what I promise. (Ah, by the way, do you have the same server? Here, Huagan Xiaofaluo, hey, did I go to the wrong set!?)

Ah... probably just my complaint =v=

The past two chapters are the seaside!I'm talking to you!This is a magical sea!If I still write the same series of articles on the beach, you will probably understand how amazing it is.

ps: Dear friends, regarding the Internet of Things competition, the emmm rules are made up randomly, just take a look and take a look.

--------------The shortest small theater in history-------------------

Everyone: Kekekekekekekekekekekekeke! ! !

Me: You collectively caught a cold, is this?

Qiu Yun: I feel like I choked on a mouthful of dog food.
