I have set up WLED on an Wemos D1 Mini (ESP8266) and that works fine. I will build this project innside an enclosure and that enclosure has an RGB led for showing different states.
But i can't install additional code (the easy way) on the flashed Wemos D1 Mini and i need to use an second microcontroller for adding states to the led.
I need the LED to light up red when the switch on the box is turned off, no power is given to microcontrollers. The red light on the RGB LED for showing standby mode must be hard wired.
When the switch is turned on, i want the RGB LED on the box show green light. But in same time i need the red light turn off....
I need some guidelines how to achieve that. The simplest way is to program the Wemos D1 Mini off course, but this is not easy in this case.
Some ruff ideas?
