Hey everyone. If you have any useful information on the below questions, please offer a quick reply.
How can I get a piezo to work as a quick-firing temporary switch as a digi-in? Are there piezos that will spit out a 5v signal? Or, are there transistors that will run/close on the <5v voltage supplied by a normal piezo?
I'm using a simple analog circuit of a piezo with a 5.1v zener diode and a resistor in parallel running to the analog inputs. I need a lot more than 6 inputs, though, so I need to adapt the sensor to be digital input capable.
The common piezo doesn't put out 5v, so it won't be read by the digital inputs as ON. Switches and pushbuttons relay a full 5v, on the other hand.
The piezo is ussed instead of a switch because I'm placing it on rubber-covered wooden panels of a percussion pad. I need more than 6 inputs, so I must go digital, and "cranking up" the signal from a piezo, or getting a bigger or whatnot piezo that WILL put out 5v, is the only way to do that.
try a search of the forum, you will find many posts on piezo's. If you want to alter the function form momentary to on/off, you could do this easily in software....
