Title: Speaker for key clicker
Post by: QuincyJones on Mon, 04 July 2016, 18:22:22

How would I create an audible 'click' for each key press - would it be a simple short burst of a square wave? In which case, I assume a small (18mm) piezo speaker would be enough amplification?

Should make an array of relays that are individually actuated for each keypress, damn that would sound so satisfying.

Like how an indicator sounds when activated in a car!

depends on your piezo speaker
what are you using for the keyboard?
