pianocktail circuit

Here is our circuit for the Pianocktail. Because we are gathering data from the 88 keys of the piano and using the piano keys as input switches we had to use shift registers to increase the legs of the arduino to allow us to have 88 inputs.



The shift register outputs will then connect to relay switches that will control our solenoid valves which will allow for the release of liquor from the bottles.


Here is a video of our circuit as we are testing it out:
