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 ...

The entire system is built on the backbone of an Arduino Uno with a few other parts totaling at about $150. That seems expensive, but DeBoisblanc's build covers a lot of ground.

The cnc lathe rev counter prototype now works – with a bit of help from friends who can actually programme. On a signal generator, the display is rock-solid and spot-on – the crystal on the Arduino ...
