Topic: Hardware vs. Software debounce (Read 937 times) previous topic - next topic


I've been finding lately that with most little projects it is easier for me to just stick a cap across my buttons than it is to put in debouncing code. 

Is there any advantage or disadvantage to doing so that I might not be seeing?  Is there a cap value that is preferred for this?  Seems like I have used everything from 1 to 100nF and been just fine.
