Nettet23. nov. 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); NettetLet's imagine that Arduino has to do two tasks: blinking LED and checking the button state, which can be pressed anytime. If we use the delay() function (described in a previous tutorial), Arduino may miss some of the pressing events.In other words, Arduino cannot fully do the second task.
