WebApr 14, 2024 · The orange LEDs on the PCB indicate that the PWM interrupt is active and the ADC is being read out. When debugging the LEDs light up briefly, but turn off shortly after and the code stops running. Wh en running the code without the debugger, they light up and remain lit, meaning the code is running.
