I am doing a mini project, and I need the following:
Connect 6 capacitive sensors TTP223 to the same input.
I have to get one of these two solutions:
get a single TTP223 to have a larger pulsed area (I have no idea how to do it).
Connect them all to the same D7 input (I have no more free inputs), but when I connect them they don't respond. I understand that it must be because when you have one it sends the 3v voltage and it must cause a problem with the other sensors. I have tried to put a M7 diode, but no matter how I put it... it doesn't work.
Someone could help me please.
