In this Tutorial we are using a Touch Sensor with Led , When you touch the sensor , Led will Turn On/Off.
Arduino IDE 1.8.5 (programmable platform for Arduino)

It outputs a signal if the metal pike of the Sensor was touched. You can adjust the sensitivity of the sensor with the controller.
The sensor has 3 main components on its circuit board. First, the sensor unit at the front of the module which measures the area physically and sends an analog signal to the second unit, the amplifier. The amplifier amplifies the signal, according to the resistant value of the potentiometer, and sends the signal to the analog output of the module. The third component is a comparator which switches the digital out and the LED if the signal falls under a specific value. You can control the sensitivity by adjusting the potentiometer.
Welcome to the Arduino Based Project which consists of Touch Sensor. The basic functionality of sensor is that it detects near proximity (also known as touch) without depending on physical contact. In simple words, you can understand that its working is same as a simple switch or circuit. When any physical medium comes in contact with the touch surface. The internal circuit will be closed inside the sensor and current starts flowing. On the other hand, when this physical contact is broken or released, circuit will be opened. Here, we are controlling a Led using Touch Sensor. When we touch the Sensor, then the led turns on or else it stays off.
