Touch Sensor Module

Course Introduction

In this lesson, we will learn how to use the Touch Sensor Module with Arduino.

Note

If this is your first time working with an Arduino project, we recommend downloading and reviewing the basic materials first.

Writing the Code

Note
You can copy this code into Arduino IDE.
Don’t forget to select the board(Arduino UNO R4 WIFI) and the correct port before clicking the Upload button.


/*
  A simple code to read input from a touch sensor
  connected to pin 7 of an Arduino Uno board.
  If the sensor is touched, the built-in LED is turned on
  and a message is printed to the serial monitor.
  If the sensor is not touched, the LED is turned off
  and a different message is printed.

  Board: Arduino Uno R3 (or R4)
  Component: Touch Sensor
*/

// Define the pin used for the touch sensor
const int sensorPin = 7;

void setup() {
  pinMode(sensorPin, INPUT);     // Set the sensor pin as input
  Serial.begin(9600);            // Start the serial communicatio
}
void loop() {
  // Check sensor state and output result
  if (digitalRead(sensorPin) == HIGH) {
    Serial.println("Touch detected!");
  } else {
    Serial.println("No touch detected...");
  }
  delay(100);  // Short pause between reads
}
