So far, I believe that we already have a basic concept for single-chip microcomputer, but why should we learn single-chip microcomputer? We need to find 10 thousand reasons for falling in love with single chip microcomputer.

Single-chip microcomputer is widely used in daily life. Various household appliances, such as washing machines, refrigerators, electric cookers, and electronic names, often refer to their own products as high-tech, fully automated, and microcomputer-controlled smart products ...... For those who have never touched devices such as single-chip microcomputer, it is really hard to imagine. After you learn SCM, your thoughts are completely different. You may just smile, and then secretly think about what MCU is used by people? How to write a program? Do you want to make a similar game in another day? Of course, I do not deny that single-chip microcomputer is not a high-tech product. I am not here to offend the appliance manufacturers. Please understand O.

Many digital products, such as mobile phones, slrs, cameras, and MP3 players, including hard drives in computers, often use single-chip microcomputer. It greatly enriches our spare time.

　　

Various billboards on the side of the road, especially at night, will always emit dazzling light, and many of those billboards are controlled by single chip microcomputer.

Single-chip microcomputer is also widely used in medical equipment fields, such as medical ventilators, various analyzers, monitors, ultrasonic diagnostic equipment and bed call systems. These single-chip microcomputer work hard day and night to help doctors create a miracle of saving lives again and again.

Many components of automobiles and even aircraft also use many single-chip computers to execute various arduous tasks. Single-Chip Microcomputer ensures our travel.

　　

Single Chip Microcomputer is also widely used in industry. Assembling various products on the assembly line is inseparable from the control of single-chip microcomputer. Various data collection, intelligent control, alarm system, and so on are all centered on single-chip microcomputer.

I know a lot of MCU applications, but it seems that there is no direct connection with our life. But this is not the case. I will give you some examples below.

When I was a child, I liked toy cars like many people. I saw that there was a remote control car in the mall, and I wanted it very much. But at that time, my family was not in good condition, so I still didn't buy it. I later thought about creating a remote control car, but it was too difficult to do so. Later, when I went to college, I came into contact with the single-chip microcomputer and found that the single-chip microcomputer was too powerful. This is also because of my interest. In a few weeks, I made a remote control car easily.

People in the dormitory often do not remember to bring the key, or it is inconvenient to bring the key out of the dormitory, such as playing basketball. Then a few people came back together, with a wide eye and no key. The door couldn't be opened, so they had to ask for help. So I installed an electronic password lock on the dormitory door, with buttons and indicators outside the door. The door contains a single-chip microcomputer and a motor, and the motor can open the door through a thin wire. You may worry about security issues, but you don't have to worry about them. Our password lock will start the motor to open the door only when the microcontroller works normally and the password is entered correctly. The password can be changed at will. You can enter hundreds of passwords as long as you want. Of course, this is completely unnecessary. The password is incorrect three times in a row, and the red light will be turned on and locked. It is forbidden to try again. It takes several minutes to unlock the password. Therefore, it is unrealistic to try the password. If the single-chip computer is not powered, or the password lock is broken, don't worry. Its working principle determines that, in that case, it is impossible to enter a password to open the door, and the door cannot be opened by the motor itself. Therefore, security is beyond doubt.

If I get up early in the morning, I often cannot get up. Refer to the online solution, I designed an alarm clock to simulate the rising sun in the morning and the room gradually fades in, the light will be slowly lit up half an hour before the alarm. Then people will wake up slowly due to the light. If the scheduled time is reached and the person is not up, press the switch to confirm that the person has gotten up, and the alarm starts to ring. In addition, you can set the switch to a location far away from the bed. Only when the switch is up can you turn off the alarm, so as not to miss the time to get up and go to bed again.

There are many other similar small production projects. For example, the heart-shaped dot matrix made by someone who made the "confession artifact" is a must-have gift for girls. There are also a variety of very beautiful clocks, digital photo frames, electronic candles, light cubes and so on. There are also foreign cool people who use single-chip microcomputer to make a variety of interesting gadgets, and even use single-chip microcomputer to make a simple e-book reader. Readers who love flight models and robots can also use single-chip microcomputer to make these things. Later, they will give some preliminary explanations on the electromechanical control of single-chip microcomputer. At the end of the article, we will introduce several project instances. If you are interested, you can try to do this.

Single-chip microcomputer is as ubiquitous as "small and strong", bringing a huge impact to our lives ......
