Introduction

Are you tired of clicking mechanic button? Well, try our capacitive touch sensor. You can find touch sensors mostly used on electronic device. So upgrade your Arduino project with our new version touch sensor and make it cool!!
This little sensor can "feel" people and metal touch and feedback a high/low voltage level. Even isolated by some cloth and paper, it can still feel the touch. Its sensitivity decreases as isolation layer gets thicker.

Sample Code

int ledPin = 13;                // Connect LED on pin 13, or use the onboard one
int KEY = 2;                 // Connect Touch sensor on Digital Pin 2
 
void setup(){
  pinMode(ledPin, OUTPUT);      // Set ledPin to output mode
  pinMode(KEY, INPUT);       //Set touch sensor pin to input mode
}
 
void loop(){
   if(digitalRead(KEY)==HIGH) {      //Read Touch sensor signal
        digitalWrite(ledPin, HIGH);   // if Touch sensor is HIGH, then turn on
     }
   else{
        digitalWrite(ledPin, LOW);    // if Touch sensor is LOW, then turn off the led
     }
}
