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 ...

Figure 1 gives a simple circuit for the PUSH ON, PUSH OFF function with only a few inexpensive components. In this design, the output is connected to the input of the gadget when you press the push ...

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 ...

We’ve embedded video of the circuit controlling an LED after the break. This IC ends up in a lot of projects so dig through your parts bin and give this circuit a try.

Using a bunch of small push buttons harvested from old CD players, he rigged this unique way of mounting LEDs. Each LED has two buttons under it. They are wired in parallel, so if either of them ...

Push button LED puck lights are pretty boring on their own. Take it apart and solder in your own colorful LED bulbs for a little holiday fun, or a UV bulb for a DIY blacklight. Polarity matters ...
