How to use touch sensor using arduino


Materials:-
  • Arduino uno= https://bit.ly/30v5XcY
  • LDR sensor module= https://bit.ly/30X7Gs4
  • leds = https://bit.ly/2RqpfMM
Diagram:-

Connections:-

Touch sensor to arduino
  • Senor VCC = Arduino 5v
  • Sensor GND = Arduino GND
  • Sensor SIG = Arduino digital pin 7
LED to arduino

  • LED ( - )  = Arduino GND
  • LED ( + ) = Arduino digital pin13  

Code:-


const int touch = 7;
const int led = 13;

void setup() {
  pinMode(touch,INPUT);//define pin as input sensor
  pinMode(led,OUTPUT);//define pin as output sensor

}

void loop() {
int y =digitalRead(touch);//read the sensor
if (y==1){
  digitalWrite(led,HIGH);//turn on led
}else{digitalWrite(led,LOW);//turn off led
}
delay(500);

}
