This is your basic LED blinking program in plain old C++, including a basic timing loop. It also includes some optional lines in the setup() block to compare pinMode memory usage between C++, direct ...

Arduino simulator window. The Arduino Sketch (code) is simple and flexible. The Delay at the end of the Loop procedure is added deliberately to avoid possible switching errors. The delay of 250ms woks ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

The current pinMode() implementation performs a digitalPinToPort(pin) and then checks the port for NOT_A_PORT but digitalPinToPort() is a program memory table read. It is possible to give an illegal ...
