This is my first post on this forum, so I hope I am doing this right. I am getting some strange behavior from the CapacitiveSensor library. My setup is just the basic capacitive sensor setup like this: [capTouch] where the sensor is a piece of metal behind some cardboard and my arduino is powere…

It is as I suspected - it is autocalibrating. Try: #include <CapacitiveSensor.h> CapacitiveSensor capSensor = CapacitiveSensor(7, 5); void setup() { Serial.begin(9600); capSensor.capacitiveSensor(1); // allow one calibration } void loop() { float sensor = capSensor.capacitiveSensorRaw(20);…
