WebDec 1, 2024 · You cannot directly connect an LED to a battery or voltage source. Firstly, because the LED has a positive and a negative lead and will not light if they are the wrong way around and secondly, an LED must be used with a resistor to limit or 'choke' the amount of current flowing through the LED - otherwise the LED could burn out! Jumper wire pack 1 WebNov 23, 2024 · Switching the LED On and Off in Arduino. The LED will turn on when we give the pin to connect a high signal level (voltage). The digitalWrite function with the second parameter HIGH is responsible for this in Arduino. For example, for an LED connected to pin 12, the command will look like this: digitalWrite (12, HIGH);
