WebFeb 8, 2014 · If you need to read in a voltage on an Arduino digital or analog input pin, ensure it is between 0 and 5V. If it is outside these limits, you can bring down the voltage using a voltage divider. This scales the input voltage to allow for analog or digital readings of voltages otherwise outside the allowed range. 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.
