You will need the Arduino Board, a 560Ω resistor, and LED and the code example below. We set the pinButton variable as integer 8 and we connect the button at pin 8 on the Board. Then the LED is ...

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

This typically includes resistors, push buttons ... some simple projects like the Blink example that only require an LED output. These basic output-only tutorials are excellent starting points ...
