Both LEDs are electrically bound and cannot be controlled independently. Those LEDs have 3 colour channels, controlled independently: R (Red), G (Green) and B (Blue). Mixing of those colours creates other ones, such as pink and violet. Each R G B channel can be controlled with a separate GPIO to switch it on or off or control brightness using a PWM signal, as presented in this tutorial. text/html 2025-07-31T09:42:18+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/iot-open/practical/hardware/rtu/esp32/scenarios/servo?rev=1753954938&do=diff ESP32 Servo This is an example of the servo running sweep program.
