Just wondering is there any recomended way to physically wire teensy3.2 analogue or touch pins to sensor pads and plates, so as to give protection to the board from short circuits or other static voltages etc. ...... so as not to alter the sensitivity of sensing too much. My project is not using actual measurement values accurately, just need to know the changes that take place so to know a pad is touched by something and teensy senses it. I have used 220 ohm resistors in series with the pins, in my mind to avoid short circuits between pins due to say cut wiring etc. Just wondering is this necessary or what other recommendations
