ARDUIN WITH TOUCH SENSOR

In this tutorial you will get to know that how you can create a touch detection system .

Material requirements are given below :-

• ARDUINO
• TOUCH SENSOR
• GREEN LED
• RED LED
• BRAEDBOARD
• JUMPER WIRES
  

Working

Whenever you touch any finger on the sensor red LED starts glowing making you alert.

Otherwise green LED glows indicating no touch.

CONNECTIONS

ARDUINO

GND          =     -ve of green , red LED and

                          GND of touch sensor

5V              =     VCC of touch sensor

2                =      +ve of red LED

3                =      +ve of green LED 

4                =      SIG/OUT of touch sensor

CODE OF THE PROJECT :-

const int touch = 4;
const int green = 3;
const int red = 2;

void setup() {
pinMode(touch, INPUT);
pinMode(green, OUTPUT);
pinMode(red, OUTPUT);
}

void loop() {
if(digitalRead(touch) == HIGH){
  digitalWrite(green,LOW);
  digitalWrite(red,HIGH);

}

else{
  digitalWrite(green,HIGH);
  digitalWrite(red,LOW);
 
}
}
