Working With Touch Sensor Using Arduino Mega

Introduction

• In this article I will explain about the Working With Touch Sensor By Using In Arduino Mega.
• When we touch the things what we have kept or connected to the arduino, it will be used to blink the LED.

Parts Of Lists

• Arduino Mega 2560
• Touch sensor
• Bread Board
• LED
• Hook Up wires

Touch Sensor

• Touch Sensor enables you to replace press with touch.
• It can detect the change in capacitance when a finger is near by.
• That means no matter your finger directly touches the pad or just stays close to the pad.
• Touch Sensor would outputs HIGH also.

Connection

Step 1: Connection From ArduinoMega To Touch Sensor,

• Connect the SIG pin to Ao of the Analog pin to the Board
• Connect the VCC pin to 5v of the Arduino Board
• Connect the GND pin to Gnd of the Arduino Board.

Step 2: Connection From ArduinoMega To LED,

• Connect the postive side to 02 of board
• Connect the negative side to GNd of board.

Programming

void setup()
{
   pinMode(2, OUTPUT);
}
void loop()
{
   if(analogRead(A0) > 600)
   {
      digitalWrite(2, HIGH);
   }
   else
   digitalWrite(2, LOW);
   delay(100);
}

Explanation

• In this article I explained about the Working With Touch Sensor By Using In ArduinoMega.
• It can clearly display the output on the LED blink
• When we touch the sensor it will glow high automatically.
