Info
Project is Done!
A 12V simple RGB controller with ESPHome support.
Idee
This project uses an ESP8266 microcontroller to control 12V LED strips (RGB) using PWM (Pulse Width Modulation) via MOSFETs, and is configured through ESPHome for seamless integration with Home Assistant.
Wiring
Connect the 12V+ from the power supply to the + input of the LED strip. The – (negative) from the strip goes to the Drain of an N-channel MOSFET. Connect the Source of the MOSFET to GND, shared with both the ESP and power supply. The Gate is driven by a GPIO pin. Ensure the ESP GND and power supply GND are connected. The ESP8266 is supplied using a DC to DC buck converter with the output Voltage set to 3.3V the input is connected directly to the 12V supply Voltage.
