This code helps to control a servo motor using a touch sensor. You can connect the wires as below. Connect the touch sensor pin to D2 Connect the servo motor pin to D9 //below is the arduino code ...

Circuit Setup: Wire up the touch sensor module to the Arduino Uno as per the circuit setup section. Code Upload: Open the Arduino IDE and create a new sketch. Copy and paste the provided Arduino code ...

A complete DIY Guide to build a Capacitive touch sensor with ESP32 with PCB design and Arduino code. Control lights or appliances with a smart touch sensor with ESP32.

The sensor forms an image and OpenCV detects the actual touch configuration. It appears you can use the raw data from the Arduino, too, but it might be a little harder.
