Hello,

I would like to know how you are designing capacitives sensors with Teensy boards and maybe have some feedback about the way I do it.

I read 26 capacitive sensors for a battery operated synth project. I use a T3.6. It works, but I wonder if there are other ways to achieve this. Here are my "recipes" :
- 26 electrodes with 2 interdigit PCB traces : 1 trace for signal, 1 for ground. My electrodes are round, 1 pouce diameter.
- FastTouch library, which can transform any pin to a capacitive sensor
- exponentiel filtering to smooth signal

Result is OK but I wonder if I could do it in simpler way.
