[Training Camp_Advanced Class] Internet of Things Relay based on ESP8266

When I first participated in the training class, I just messed around on my own for almost half a month. Every time the teacher taught me, I refreshed my knowledge. When I got to the drawing board, I probably finished the drawing on Sunday morning as the teacher said, but I didn’t finish it before going to work. Hit the board. Later, on the evening of August 10, the teacher reviewed other people's homework and discovered many problems of my own. For example, the AC power line was not widened, filter capacitors were not added, and copper was laid around the antenna... After looking at the students' works, I feel that there are many things worth learning. Among them, wiring is also a knowledge. I learned how to discharge capacitors, how to avoid strong and weak currents crossing, and the beautiful wiring of the students. Learning new things is fulfilling for me! It is now 1:30 in the morning on August 12th. I have just finished modifying the pictures and placed an order. Thank you to Chen NPC for your corrections and popular science on the placement of capacitors when collecting the coupons! ! ! 8/18 I spent a lot of time during this period and really learned a lot. Since the inverter is still on the way, I haven’t perfected the board and now I have to hand it over. Let me introduce it. The shape is designed to fit into a housing. , I chose esp8266 because I had given up on it before. The biggest mistake was not using two microcontrollers to control it. esp8266 was developed using Arduino. I used Alibaba Cloud before. When I did the last step, my mobile phone was not equipped with the Internet, but I could debug online. So I gave up and chose Blinker. After the modification, the temperature can be displayed. However, after adjusting it for a long time, I don’t know why I can’t control the IO port through the buttons. I usually copy it from the routine, but I don’t know why the routine can’t burn. Log in, (the development board cannot be found), I don’t know if it is a problem with my module. Sometimes it just works by unplugging and plugging it in like this, but this routine just can’t be burned in. I also added Tmall Genie control and OLED display. , 3D printing, I really learned a lot during this training camp, using sensors and displays, what should be paid attention to when designing circuits, learning a little bit of modeling from scratch, how to read source code, etc., driven by progress I have experienced a fulfilling life, and the progress has also allowed me to discover what I am like in self-study. I am very grateful for this opportunity. It has been greatly improved compared to before. I really learned a lot. Thank you Lichuang EDA, No. 8-18 The late response components have arrived, and the Tmall Genie control light simulation relay and the mobile phone APP control light relay have been completed. The solution to the problem: The reason why the app cannot be used to control the switch is that the GPIO mode is not defined. Tmall Genie Just add the heartbeat package and associate it with the corresponding app to achieve Tmall Elf control! ! ![3d.jpg]
