【Solicitation Order】WiFi Intelligent Controller

### Project Introduction The cool lamp used in the dormitory can only be turned on and off manually. I often forget to turn off the light when I go to bed, and then come back again. In the summer, I often forget to turn off the small fan when I go out. . . , it is really not smart, now we are making a controller that can easily manage these devices - - - ### Project function introduction * TypeC or soldered USB cable for power supply; * Three devices can be controlled by local switch, and the local button control function has been completed ; * The beautiful shell is ready, but needs to be optimized; * Try to make an APP to control all devices via LAN, to be made; * If the previous article is inconvenient to use, you can upgrade to Mijia to achieve Xiaoai voice control; - - - # ## Project properties* [x] Schematic design* [x] PCB design* [x] PCB proofing* [x] Welding test* [x] Shell design* [x] Functional test* [x] Program test- - - ### Circuit explanation is relays and buttons plus basic peripheral circuits - - - ### Pictures![9KofGfqiK08pMLrFs2GPYRAoH1as0evYHD3Y4v50.jpg] ![rHlqIo28YY2OP0P9AlTIMG3rZDtzUTeKnNG3JEFJ.jpg] ![IMG_20211210_004 819.jpg] ![CWWed1ybffB7V3WvKWOjjwt2hjoihAMqYoTMa8fN.jpg] ![IMG_20211210_004836. jpg] - - - ### Demonstration video [B station video](https://www.bilibili.com/video/BV1M44y1a7NU?spm_id_from=333.999.0.0) - - - ### Notes It is recommended to put The burned VCC and the relay power supply VCC are distinguished, otherwise the pin level jump during the burning program will affect the relay on and off; after testing, it was found that the first generation of the shell needs to add a section of support, and the open source model will be optimized later * Attachment A_Ctrler01 is Currently there is only code for local key control functions
