What current limiting resistor value should you use if you have one LED and want to power it with a supply voltage of Vs = 3.8V? To calculate the current limiting resistor, you first need to look in the datasheet (always RTFM first!) for the LED's recommended forward voltage and forward current specifications. In this example, they …
