【Training Camp】IoT RGB Lamp-662104A

Overview

The project basically follows the training camp video tutorial to implement the main control part: use the WB3S module from Tuya Smart and set the pin parameters. The 0-code programming solution is chosen, so the setting is very simple, but 0-code means it is not extendable. ps: Be sure to confirm the firmware parameters when purchasing the module. The 0 code module parameters are fixed and cannot be changed once shipped. I bought the wrong one the first time (I bought a module from another plan with mismatched pins)
——— ——————————————————————Power supply part: According to the video tutorial, the AMS1117-3.3v chip is used for voltage conversion, so that the USB input 5v can be converted into one that can be used by WB3S 3.3v
——————————————————————————Drive part: use PWM drive, cooperate with MOS tube to light up an RGB lamp
