What lamp do you use?

I used 1W RGB LED with a 15° 20mm lens found on aliexpress, the lens is smaller than the hole and I filled the space with paper and glued everything in place.

I used three LED drivers based on CN5711, you can use the small trimmer on the boards to regulate the amount of max current for your specific LED. You can drive the boards with PWM over the CE pin, you can connect this pin directly to an output pin of the mcu. The LED boards must be powered by 5V but they happily accept 3v3 on the CE pin.

Unfortunately I did not draw a schematic for this project but it's pretty simple:

• connect power (+5V - VUSB pin) and GND to the 2 servo
• connect power (+5V - VUSB pin) and GND to the 3 LED drivers
• connect D1 -> pan servo motor
• connect D2 -> tilt servo motor
• connect D5 -> to the red LED driver CE PIN -> the output goes to the anode (+) of the RED led
• connect D6 -> to the green LED driver CE PIN -> (same but for green)
• connect D7 -> to the blue LED driver CE PIN -> (same but for blue)
• connect the cathode (-) of the LED to GND

You can change the default pins here https://github.com/ghidosoft/esp8266_moving-head/blob/main/src/main.cpp#L23
