ESP32 Capacitive Touch Pad Example
The following 10 capacitive touch pads are supported for ESP32. Use the function touch_pad_set_fsm_mode () to select if touch pad measurement (operated by FSM) should be started automatically by a hardware timer, or by software. If software mode is selected, use touch_pad_sw_start () to start the FSM. Touch State Measurements

ESP32 Touch Pins ESP32 has 10 capacitive touch-sensing GPIOs. When a capacitive load (such as a human skin) is in close proximity to the GPIO, ESP32 detects a change in capacitance.
ESP32 Capacitive Touch Sensor Pins with Arduino IDE Random Nerd Tutorials
Arduino-ESP32 TOUCH API TOUCH common API touchRead This function gets the touch sensor data. Each touch sensor has a counter to count the number of charge/discharge cycles. When the pad is 'touched', the value in the counter will change because of the larger equivalent capacitance.
[E04] how to use esp32 capacitive touch sensor pin controlling AC appliances using esp32 touch
ESP32 Touch Pins. The ESP32 has 9 capacitive touch-sensing GPIOs. When a capacitive load (such as a human finger) is in close proximity to the GPIO, the ESP32 detects the change in capacitance. You can make a touch pad by attaching any conductive object to these pins, such as aluminum foil, conductive cloth, conductive paint, and so on. Because.
