If you have a noisy signal, like a switch, you often want to "debounce". That means, ignore rapid changes (noise) in a signal after it changes. e.g. a switch is often configured as HIGH when open, and ...

This library is probably the simplest button debounce ulitity for Arduino. The code is based on Jack Ganssle's debounce function that he described in his part 2 of "A Guide to Debouncing" article.

3. Switch Debouncing IC. There are ICs available in market for switch debouncing. Some of the debouncing ICs are MAX6816, MC14490, and LS118. Below is the circuit diagram for switch debouncing using ...

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.

Most debounce circuits shorten or lengthen the time a switch is pressed to obviate interference pulses caused by switch bounce. The present circuit does not affect that time: the pulse at the output ...

Did you know that you can use Arduino to turn on an LED when you press a ... int stateButton; int previous = LOW; long time = 0; long debounce = 200; void setup() { pinMode(pinButton, INPUT ... I ...
