Hi Guys,

I am creating a matrix with 12 cap sense buttons.

Do I need a send wire for each port or can I just use 1 for all the digital inputs, I am using capacitiveSense04 library ?



According to the example sketch you can, though it only uses 3 different recieve pins, guess you'll just have to try more. I have never used more than one because I use it on ATTiny85s to read the level of waste tanks and send the results to a main UNO.
