Tutorial: How to use the HTTM touch button sensor module

The HTTM touch button sensor module is a green capacitive switch that detects the presence of a finger without physical contact. Ideal for consumer electronics projects and prototypes, it is easy to integrate into Arduino and other microcontroller circuits.

What you need

• Arduino Uno
• USB cable
• Connect to computer
• Arduino IDE software

Steps

1. Install the Arduino IDE software on your computer.
2. Connect the Arduino Uno to the computer via the USB cable.
3. Open a new tab in the Arduino IDE software.
4. Insert the example code from step 5.
5. Upload the code to the HTTM module.
6. Verify the pin connections of the HTTM module with those of the Arduino Uno: GND to GND, VCC to 5V and OUT to a digital pin of the Arduino.
7. Open the Serial Monitor in the Arduino IDE to view the input data from the module.
8. Test the touch button by pressing it and observe the response in the Serial Monitor.

Example code

const int buttonPin = 2; // definisci il pin digitale collegato al modulo HTTM void setup() { pinMode(buttonPin, INPUT); Serial.begin(9600); } void loop() { int buttonState = digitalRead(buttonPin); // leggi lo stato del pulsante tattile Serial.println(buttonState); // invia lo stato del pulsante al Serial Monitor delay(100); // attendi 100 ms prima di rilevare di nuovo lo stato del pulsante }

Mini project

Create a home security system that activates an audible signal or an LED when the HTTM module is pressed.

Common mistakes

• Do not verify the correct pin connection.
