Bouncing switches in your Arduino projects? Easy ways to fix it! 

Very important topic, especially when a project interacts with the "real world!"

You can also use else if {} instead of else { if {} }

Very elegant using the millis fonction!! Thanks !

Thx Yvan !! , always fall in those doubts.... despite I ‘ve already used many times “ buttons “ , in getting old and can’t remember this useful code .

You can use jc-button library as well..

16 years ago !... I used a de-bounce subroutine in a Microchip pic12F508 ...

Merci Yvan !! Joyeux Noël eet bonne année !

thank you sir!

Great topic, can you recommend a debounce library

Thanks a lot, nice demonstration.

Hi. I'm novice in Arduino and I enjoy to watch Yours tutorials. I was reading the code for this tutorial and I think that bouncing switch part is wrong. I think that code: if ((millis() - TimeOfLastDebounce) > DelayofDebounce) will be true most of time, and there will be no time out. Sorry if I'm wrong. Please comment this. Best Regards.

Where is your head? ! The code would be nice too. ☺

Delay is not usefull, make it only with Timer polling.
