[Internet of Things] Hongmeng WIFI switch

This is a robot switch based on the ITCAST-HI3861 module and MG996R servo. ITCAST-HI3861 is a wifi module developed using HiSilicon HI3861 chip. It is suitable for Hongmeng openharmony equipment development and wifi IoT software development. This production is for installation Outside the traditional switch, there is no need to modify the original switch circuit. Use the mobile phone to control the servo to rotate at a certain angle through the WIFI module to simulate the human hand pressing the switch. Novice production and testing steps: 1. Draw the PCB with reference to the schematic diagram, go to Jiali Chuang to build the board, purchase the ITCAST-HI3861 module and other peripheral components, and prepare the MG996R servo and TTL programmer. 2. After soldering the board, connect the USB power supply, MG996R servo and TTL burner, and use the attached burning tool HiBurn.exe to burn the firmware Hi3861_wifiiot_app_allinone.bin into the module. 3. After pressing the RST key to restart, you can press the manual button to control the servo to rotate forward and reverse to a certain angle to change the status of the rocker switch. 4. Mobile phone WIFI control: Connect the mobile phone to the module WIFI: genkipi-switch Password: 12345678, then open the web page http://192.168.10.1 to enter the module control page. 5. Students with coding skills can unlock more ways to play. 6. The shell design of Lichuang EDA Professional Edition is also a very convenient tool, which is simple and easy to use. The shell 3D file is attached below. ![31.png] ![32.png] ![33.png] ![1648625874213.jpg]
