The issue here is that the ESP32 ADC inputs only go up to 3.3V and would give an incorrect maxed out reading for anything over about 6.4A: WebTo match the circuit diagram we will use A3: pinMode(A3, INPUT); and then do the analog to digital version by using the analogRead () command: int x = analogRead(A3); //Reads the analog value on pin A3 into x. The value that is returned and stored in x will be a value from 0 to 1023. The Arduino has a 10-bit ADC (2^10 = 1024). incompatibility\u0027s p5

"WebNov 11, 2024 · First of all, light-emitting diodes always need a current limiting resistor. In this case apparently at least (5V - 0.8) / 200mA = some 20-25 ohm at the very least. Otherwise you risk burning the diode. Second, the output current of your MCU is not 40mA per pin! 40mA/pin and 200mA total are absolute maximum ratings. " - Read current arduino
