Compared with mobile phones, the construction of this password electronic lock is much simpler. The core component is the chip, and the important functions are completed by this chip.

Zhong Yue quickly figured out how it worked, and now, it was time to add new functions to its existing functions.

First of all, it should be able to connect to WIFI, so that the picture taken by the camera at the gate can be transmitted over the network. That way he can check it on his phone at any time.

Then, have an alarm system that will sound on his cell phone whenever someone tries to open the gate.

Finally, connect a high-voltage wire, and if it is found to be a thief, pass guò remote control zhì, and the person will be corona. The point is not to electrocute people.

"So the door is foolproof, and what about the windows?" he looked at the window, even though it was eighteen floors, I was afraid that it would not be difficult for some good snitches.

"Well, all windows should also be equipped with alarm systems. ”

Thinking of this, a flash of inspiration flashed in his mind, "Just transform all the household appliances, get a home control system, and then everything will be fully automated." ”

He felt very excited when he thought about that scene. With great enthusiasm, I started to design.

However, this is not a job that can be done in a moment. All electronic products are a system engineering, the more complex the system, the more parts involved, the more troublesome it is,

Just like a mobile phone, if you want to add a new function, it doesn't mean that you just add a component, but also consider power consumption, heat dissipation, and so on.

These days, he also tries to learn from various brands of mobile phones, trying to "develop" a mobile phone with full functions, and it turns out that there are many problems.

At that time, he knew that the development of electronic products was not as simple as he thought.

He knew that the biggest problem was still with himself, and his knowledge of electronics was too poor.

"It seems that if you have time, it is better to go to the university and recharge. ”

When the newly made chip failed again, this thought flashed through his mind.

………………

Zhong Yue's house is half a month. In the past half a month, he has only been to the store twice, both of which are to send a new mobile phone, put down his things and leave.

The most valuable thing in the store is the mobile phone, which is counted. Besides, there are cameras in the store. He was very relieved to hand over the shop to two people, and he was not afraid that they would make a ghost.

Until one morning, after he finished exercising, he just got home and received a call from his mother.

As soon as I picked it up, I heard my mother's complaint, "Ah Yue, why are you not at home early in the morning, where did you go?"

He laughed and said, "Mom, why didn't you call me beforehand, I moved." ”

"Why did you move?"

"I'll tell you then, you're where I used to live, aren't you? I'll pick you up. ”

"It's not me, it's your aunt's son Huang Qiuxun. ”

After listening to his mother's explanation, he realized that it was his aunt's son and his cousin who came. Because of the college entrance examination to get into the university here, I wanted to take advantage of the summer vacation to come over to familiarize myself with the environment, so I specially asked his address and wanted to live with him for a few days.

Last night, this kid took someone else's hitchhike. Because he was driving a night train, the owner kindly sent him downstairs to the place where Zhong Yue used to live.

Unexpectedly, after knocking on the door for a long time, no one answered. The mobile phone was out of battery again, so I had to call home from the public phone, and then find Zhong Yue's mother and call Zhong Yue's mobile phone.

After figuring out the whole thing, Zhong Yue hurriedly changed his clothes and went out, it was not yet seven o'clock, and his cousin was not familiar with his life, and he couldn't be contacted, so it was better not to have anything happen.

Downstairs, he went straight to the subway station. It's hard to take a taxi at this point, and it's not as fast as taking the subway.

At this time, there are many people who take the subway, and most of them are students wearing school uniforms.

Zhong Yue grabbed the rail, put on a Bluetooth headset, and called his aunt's house first and asked for his cousin's mobile phone number. Just as I was about to hit it, I found a familiar figure on the other side.

"Is that her?"

It was the schoolgirl who smashed one of his milk cartons at the garbage point half a month ago. Today she had a pigtail on her left side, which she didn't recognize just now. She was with a female classmate, facing this side.

"Would you like to say hello?"

He thought to himself that when he finished exercising every morning, it was almost the time for her to go to school, and he would often meet downstairs, and he could be regarded as an acquaintance.

But thinking about her usual cold fan, he still dispelled this idea. Lest you be bored.

Just as I was thinking about it, I saw her say a few words to her classmates, and walked over to her.

"Can you lend me your headphones?" asked the girl whispering, looking at the headphones he was wearing in her ear.

Zhong Yue took off his headphones and handed them to her, "You mean this?"

The girl seemed to breathe a sigh of relief, carefully pinched the headphones, pursed her lips, and said, "What time do you get off work?"

"Huh?"

"I left school at four o'clock in the afternoon, and I was waiting for you at the subway station at half past four. ”

Knowing that she had misunderstood, Zhong Yue didn't explain, and nodded with a smile.

The girl returned to her classmate and connected the headphones to her phone.

"Xiuxiu, who is that man?" the classmate asked.

The girl named Xiuxiu replied casually, "An uncle who lives downstairs." While auditioning, "I won't miss Wang's new song now." ”

The classmate was a little worried and said, "Didn't you say that it was released at nine o'clock, and it was in class at that time, what should I do if the teacher found out?"

"Ah, if I put my hair down, the teacher won't find out. ”

………………

When Zhong Yue picked up his cousin, it was already eight o'clock.

His cousin Huang Qiuxun was squatting at the entrance of the building, holding a bun in one hand and a bottle of mineral water in the other, eating deliciously. When he saw him coming, he jumped up and shouted, "Brother, you're finally here." ”

Zhong Yue looked at him and couldn't help but want to laugh, "Don't eat this, let's go, brother will take you to eat something delicious." With that, he helped him carry his suitcase.

Huang Qiuxun threw the bun in his hand into the trash can and followed.

Young people like foreign fast food, Zhong Yue took his cousin to the nearest KFC and ordered some breakfast.

"Why is your phone out of battery?" Zhong Yue was speechless.

Huang Qiuxun is six years different from him, the generation gap is still very deep, and the two families are not close, so there are not many intersections. They basically didn't play together. Especially after he went to college, he saw him a few times when he went home for the Chinese New Year. That strangeness will be difficult to get rid of for a while.

Huang Qiuxun's face collapsed suddenly, and he said bitterly, "It's not that there is no power, it's broken." Just bought it last month. ”

Zhong Yue's heart moved, and he said, "Coincidentally, I'm learning to repair my phone, take it out and I'll take a look." ”

When Huang Qiuxun heard this, he wiped his hand on his body, took out a mobile phone with a cracked screen from his pocket, and looked at him hopefully, "Brother, can you fix it?"

Zhong Yue glanced at it a few times, the mobile phone is Huawei's latest one, except for the cracked screen, everything else is intact. Nodding affirmatively, "It's good to change the screen, it's very simple." I'll fix it for you when I get back. ”

"Thank you, brother. Huang Qiuxun was overjoyed and thanked him again and again.

"My own family, what's polite. ”
