Before tackling the debouncing problem, let’s pause to think about when button bounce matters. As demonstrated above, it’s only the effective number of button presses that we and the microcontroller ...

In our minds and our computer screens, we live in an ideal world. Wires don’t have any resistance, capacitors don’t leak, and switches instantly make connections and break them. The truth is, though, ...

Among other interface problems, contact bounce complicates the connection of mechanical contacts or any noisy digital input signal to a microcontroller. Although designers have proposed a variety of ...

It used to be common to use an SR latch to debounce an SPDT switch, but how does this actually work in the nanosecond time domain? Readers may remember that some time ago, I wrote an article on switch ...

What causes a switch to bounce, and how many times will a switch bounce? Methods of debouncing a switch. What is NoBounce technology? Most people, especially non-engineers, tend not to think about ...
