1. Self/team introduction

  小生现大二，就读于邯郸学院机电学院，在修太极文化学院双学位，专业为机械设计制造及其自动化智能制造，业余爱好电子制作，从小学四年级开始接触物理，初中开始翻看高中物理书籍，热爱动手制作东西，学习太极全刀剑扇等，于高中接触网页电路绘制软件（立创EDA）当时很震惊，因为在网上找了很多，就这个非常实用。伴随我走过了多个学习生涯！

 小生在校期间积极参加各类活动，担任电子科技协会副会长一职，校科协第二负责人，组织参加各类活动，曾参加过电子设计大赛并获得三等奖，两次轻松智能大赛一等奖，邯郸市太极拳械展示交流赛太极团体一等奖。三好学生以及优异的专业成绩。一项专利以及实习经验。我的希望是能为大家用最少的资金做出最实用的产品服务大家！

2. Briefly introduce the project

This project aims to transform the equipment near the outdoor door, embodying the flexible configuration of the Internet of Things. It can complete the door lock switch of the outdoor door, the switch of the internal and external door lights, the switch of the water pump, the control of the automatic lighting at night, and the use of the outdoor door at a low price. It can be controlled indoors and outdoors by touch, and has the function of alarming and automatically turning on lights at night by human body induction. The cost is also very low, about 20 yuan, and it is easy to use, safe and reliable. [Please fill in during the competition stage↓]

1. Describe project details

Everything comes from accidents in life. Once I went home without a key and climbed over the wall into the yard. So why not get a device that can open and close the door controlled by a mobile phone? Okay, let’s mark this idea first.

One time when we were watering at home, we needed to put water into the water tank. I was at the electric switch, and my father was holding the water pipe. It was full! close! I turned on the switch, and there was a big spark. How dangerous it was, and two people had to do it together. Emmmm, can we use the Internet of Things to improve it? Of course, the output of the small gpio is only 3V, but our equipment has 220V, don’t worry! We have a solution! Finally I succeeded! Please see the video for details hehe~

I bought a door light on Taobao once. Oh my god, 30 yuan for two is so cheap, but the switch looks too ugly when placed outside. Emmm, it is connected to the Internet of Things! Then there are new features! Two-way LED store control!

Oops, what should I do if I don’t bring my mobile phone when seeing guests off and can’t turn on the door light? It's okay, we can make a touch switch to control it! Great idea to take note!

Once I went home and closed the door, it was so dark. It would be great if the lights could turn on automatically! It’s okay~ Good idea to mark it (I used the infrared sensor later, and then controlled the indoor and outdoor lights~)

There is a thief! If nothing happens, we can make an alarm device! The combination of camera and IoT module is completely Ook!

Our Internet of Things also has temperature and humidity detection functions, as well as scheduled light switching, Tmall Genie control, and computer and mobile phone control functions!

The most important thing! cheap price!

 2. Describe the challenges faced by the project and the problems solved

The challenge is to reduce costs! ! ! How to use 3V microcontroller signal to control the operation of 220V high-power water pump? How to automatically turn on the lights for 3 minutes when someone comes at night? How to make the light switch easily accessible on the circuit board? What if you make a device that can open and close the door lock instead of a person? How to make equipment more reliable and intelligent?

The above problems have been solved. The additional functions that I want to add now are: automatically opening and closing the door and installing infrared monitoring on the courtyard wall. The price is less than 30 yuan, plus fingerprint unlocking and card swiping or password unlocking (due to time reasons and financial reasons). I haven’t done it yet. I have done it before with arduino card unlocking and password unlocking. It’s just a simple combination. But I don’t have enough funds and I’m just a small student. Alas~)

3. Describe the key points involved in the hardware and software parts of the project

The key point of the hardware is the flow direction of the voltage signal. Try to avoid signals greater than 3V from flowing back to the microcontroller and try to avoid voltage fluctuations. The key point of the software is programming. How to make the various programs work together normally and work properly is worthy of careful study. , the final finished program has been placed in the attachment. Please see the video introduction at the end of the article for how to use it.
