Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Which I don’t remember hearing of before, and looks inherently bounce-proof too – if the circuit I have come up with joes the job properly. And it would have made a rather nice alternative interface ...

As if you already weren’t agonizing over whether or not you should build your own arcade cabinet, add this one ... Arduino code sees the button getting pressed, it brings the corresponding LED ...
