this is for a halloween project im messing with,i want to use my electric keyboard to activate a prop when a certain key sequence is played, if i could do this with a small programmable card that would be great
-keep in mind i know-i could just wire it all manually to where the switches(piano keys) are chained in sequence so if you only push 2 of the switches out of 3-4 it will not complete the circuit to activate the relay.-but if i can make a program that remembers many sequences by rythem and sound level (keys are pressure sensetive on 2 levels low and high) it would save alot of wiring and it could be very useful in other parts of the haunt.any ideas
