LINK : TOUCH SENSOR LINK

Aim

To interface a touch detection sensor with an ESP32 microcontroller and control an LED based on touch input for understanding digital sensing and switching operations.

Requirements

Hardware Requirements

• Espressif Systems ESP32 Development Board

• Touch Sensor Module

• LED

• USB cable

• Jumper wires

• Breadboard

• Computer or laptop

Software Requirements

• Arduino IDE

• ESP32 Board Package

• USB Driver for ESP32

Procedure

1. Connect the touch sensor module to the ESP32 board using suitable GPIO and ground connections.

2. Connect the LED to the output pin of the ESP32 board.

3. Supply power to the ESP32 board through a USB connection.

4. Open the Arduino IDE and select the appropriate ESP32 board and communication port.

5. Create a program to configure the touch sensor pin as an input and the LED pin as an output.

6. Write the logic to detect touch input from the sensor and change the LED state accordingly.

7. Compile the program and upload it to the ESP32 development board.

8. Touch the sensor surface and observe the LED response.

9. Verify the sensor operation by monitoring the output behavior during touch detection.

Result

The touch sensor was successfully interfaced with the ESP32 board, and the LED responded correctly based on touch detection input.
