What a wonderful idea
So, if I understand correctly, the makey makey module acts as a 3 trigger input to the cardboard sequencer.
When turning the sequencer, these inputs will be turned into 1 output.
But this output will be a sequence of pulses.
How can these control the arduino ?
I think the other way round would be more fun, 1 input to 3 outputs ( which can also be done with this cardboard sequencer). Then these individual outputs connected to the arduino, which will trigger 3 different sounds.
What do you think ?
P.S. Can we put this in a new thread ?
