How do you know what key a person pressed on a piano, and then translate that information on to making a cocktail? Our approach to the first part of that question is making a circuit that has 88 input switches to detect every single key in the piano. This is what the circuit is looking like so far. You can see 11 shift registers(shift-in) in a parallel set up to detect the keys and 6 shift registers (shift-out) to trigger the liquid to flow. I am having trouble with the signal past the 5th shift register. I have yet to figure out if its a voltage issue or a software issue.
I’ll keep you posted.
