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 ...

each button only changing the resistance between the two wires. The button states could easily be read by using an Arduino’s analog input. A Pro Mini model was chosen for its small size as it ...

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

It works like you’d probably expect — the light moves back and forth between the two players ... it hit your red LED and you’ve lost a point. But if you can push your button while your ...

The new UNO R4 board comes in two versions, with and without Wi-Fi connectivity ... “So for instance, you can have one Arduino with a button, another Arduino connected wirelessly with an LED, push the ...
