Make sure your Jumper wire used for capacitive touch is connected to pin D4 of the ESP32. This should be labelled on the ESP32. If you’re using conductive material to create an extension of the jumper wire used for capacitive touch, make sure it is '''firmly''' touching the end of the jumper wire and it is not loose.[br] The device sets the sensitivity of the capacitive touch when the device initially turns on. Please try not to touch the capacitive touch wire in the first second of powering up as this can affect the sensitivity.
