Arduino Uno Touch Sensor

Project Overview

This project demonstrates how to use a capacitive touch sensor module with an Arduino Uno. The touch sensor detects touch or proximity, triggering an action in response to the input.

Components Needed

• Arduino Uno
• Capacitive Touch Sensor Module
• Jumper Wires

Circuit Setup

1. Connect Touch Sensor Module to Arduino Uno:
   • Connect the signal pin of the touch sensor module to digital pin 2 on the Arduino Uno.
   • Connect the power (VCC) and ground (GND) of the touch sensor module to the respective power and ground pins on the Arduino Uno.

Instructions

1. Circuit Setup:

   • Wire up the touch sensor module to the Arduino Uno as per the circuit setup section.

2. Code Upload:

   • Open the Arduino IDE and create a new sketch.
   • Copy and paste the provided Arduino code into the sketch.

3. Testing:

   • Upload the code to the Arduino Uno.
   • Open the serial monitor with a baud rate of 9600.
   • Observe the output indicating "Touch detected" or "No touch detected" based on sensor input.

Applications

• Interactive Projects: Use in projects where touch-based input is required, such as interactive displays or input controls.
• Proximity Sensing: Implement proximity sensing applications without physical contact.
• Education and Prototyping: Learn about capacitive touch sensing principles and Arduino integration.

Notes

• Ensure the touch sensor module is positioned correctly and calibrated as per its specifications.
• Experiment with sensitivity adjustments and debounce techniques for reliable touch detection.
• Explore advanced capacitive touch sensor modules for extended functionality and integration possibilities.
