This push-button circuit can be used with a wide variety of PMICs. For example, this circuit can be used to drive a control pin, which enables and disables the buck converters, for the TPS65086 device ...

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 switch to ...

[pros] has come up with a very elegant way of making lighted buttons (translated). Using a bunch of small push buttons harvested from old CD players, he rigged this unique way of mounting LEDs. Each ...

This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...
