Debouncing button or switch inputs on microcontrollers can be a challenging problem for those first starting to program these devices. Part of the reason for this difficulty is that real-world butt… ...

For Arduino, we’re talking digitalRead(pin_whatever) == 0. ... Yep, poor switch debounce using an RC circuit. Changing to the cross-coupled SR flip-flop solved the problem.

A debouncing circuit can remove the resulting ripple signal to provide a clean transition at its output. Simply put, debouncing prevents extra activations or slow functions from triggering too often.

Digi-Key Electronics has signed a worldwide distribution agreement with LogiSwitch, makers of the Arduino-friendly NoBounce line of ICs and switches. LogiSwitch’s adaptive NoBounce technology ...

The circuit operates as follows: When the switch closes, the gate of Q2 is pulled down, driving Q2 "on." This, in turn, drives Q1 "on." Q1 shunts the switch, effectively providing a momentary ...

Called the Protected Switch Shield, it is also compatible with the firm’s own XMC microcontroller kits which borrow the Arduino form factor. The shield runs from 8-36V and provides a driver circuit ...
