Touch Light


Using Arduino and touch capacitive sensing, you can create a touch light that responds to human touch. By programming the Arduino to detect changes in capacitance when a conductive object, like a finger, approaches the touch sensor, you can trigger actions such as turning an LED light on or off. This project involves setting up the wiring, writing code to interpret touch inputs, and refining sensitivity for optimal performance. It offers an interactive and customizable way to control lighting, with potential for expansion by integrating additional sensors or functionalities.

// BY Arduino Techy
                      //
#define tsPin 2  // touch sensor pin
int ledPin = 3;  // led pin
 
 void setup()
 {  
     Serial.begin(9600);       //sensor buart rate
     pinMode(ledPin, OUTPUT);  // led
     pinMode(tsPin, INPUT);    //  touch sensor 
     } 
  void loop() 
    { 
      int tsValue = digitalRead(tsPin); 
      delay(100);
      
      if (tsValue == HIGH)
        {  
           digitalWrite(ledPin, HIGH); // led on 
           Serial.println("TOUCHED");
           }  
     else
        {    
         digitalWrite(ledPin,LOW);     // led off
             Serial.println("not touched"); 
          }   
      }
