Features

• Compatible with Arduino and other microcontrollers
• Includes relay module for controlling electrical devices
• Capacitive touch switch TTP223
• Versatile: can be used as a touch switch, key, jog latch, or CAN interface

What it is for

The TTP223 module is ideal for projects that require an intuitive and simple user interface. It can be used as an intelligent light switch, integrating the touch sensor with a relay module to control a lamp or an electrical device.

Tutorial: How to use Touchscreen Module TTP223

The TTP223 module is a capacitive touch switch that can be used to add touch inputs to Arduino projects. It is ideal for beginners and makers who want to create intuitive user interfaces without complications.

What you need

• Arduino Uno or compatible
• USB cable
• Breadboard
• Circuit connection

Steps

1. Connect the TTP223 module pins to a digital interface of the Arduino (e.g., D2)
2. Check the power supply voltage and ensure it is between 5V and 12V
3. Load the Arduino sketch to read the touch button
4. Test the user interface by pressing the touch sensor
5. If necessary, add a relay module to control larger loads
6. Check the datasheet specifications for any additional configurations
7. Try to create an application that responds to touch commands
8. Customize the user interface with a 3D print project

Example code

const int touchPin = 2; // collegamento al pin digitale
void setup() {
  pinMode(touchPin, INPUT);
}
void loop() {
  int val = digitalRead(touchPin);
  if (val == HIGH) {
    Serial.println("Touch detected");
  }
}

Mini project

Create an intelligent light switch with the TTP223 module and a relay module. Connect the touch sensor to control a lamp or an electrical device.

Common mistakes

• Incorrect power supply
