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 ...

PIC, AVR, and Arduino are ubiquitous in projects these days and a lot of the time it’s easy to over-complicate things with their use. In this case, [Tod] wanted to use a momentary tactile swi… ...

After I proposed: PIC reset and I/O on the same push-button? K Wittingham responded: "Why not use a D-Flip Flop Switch connected to clock and via an RC to the Data input. Release switch quickly data ...

Extending Woodward's original "Flip ON Flop OFF" for AC voltages, switching power ON and OFF using a pushbutton or a ...

The 486 that [someyob] is restoring had the Turbo button, but sadly there was just a simple LED to show whether or not it was engaged.

An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape.

I am trying to design a little circuit to control a light. It is supposed to be a one-push-button affair, with a long push for something and a short push for something else. One crucial thing is, that ...
