I'm working on a project, it's basically a hand-drawn paper keyboard based on capacitance.
I was thinking I can multiplex the different lines with shift register (74HC595) and switch (4066), and as I've got a lot of these here I gave them a try. But apparently not...
So I'm looking for a solution.
I've already found that : Multiplexer for Capacitive Sensors (MUXC01)
Can you confirm that this component could work or do you have any better idea about how to multiplex these keys ?
