Introduction
Capacitive sensor deals with capacitance or in simple words capacitor. A capacitance is built between the sensor and the human body when we bring a human body near the sensor. A charge is induced and this charge is picked by the sensor and is translated as a button press. As we move our finger back from the sensor plate the capacitance is lost and circuit breaks.

Hardware Preparation
This is the hardware connection and the components needed.
Sample Code
| #include <Servo.h> | |
| Servo myservo1; | |
| Servo myservo2; | |
| int touchSensorPin = 2; | |
| int touchSensorState = 0; | |
| void setup() { | |
| myservo1.attach(9); | |
| myservo2.attach(10); | |
| pinMode(touchSensorPin, INPUT); | |
| } | |
| void loop() { | |
| if (digitalRead(touchSensorPin) == 1) { | |
| myservo1.write(180); | |
| delay(15); | |
| while (1) { | |
| myservo2.write(0); | |
| delay(1000); | |
| myservo2.write(180); | |
| delay(1000); | |
| if (digitalRead(touchSensorPin) == 1) { | |
| myservo1.write(0); | |
| delay(1000); | |
| break; | |
| } | |
| } | |
| } | |
| else { | |
| myservo1.write(0); | |
| delay(15); | |
| myservo2.write(180); | |
| delay(1000); | |
| } | |
| } | |
