Flex Sensor - | Interfacing Flex sensor With Arduino and control Servo Motor

in this tutorial you will learn about the interfacing of flex sensor with Arduino and control LED and servo motor it's a very quick tutorial and I hope you will like it.

Flex Sensor 

Flex Sensor basically also known as bend sensor and what happen when you bend it, it works in the principle of capacitance and resistivity but some pressure exerted on the surface it's resistance will decrease and when you release it its resistance becomes higher,

Circuit Diagram of flex sensor with Arduino and Servo

Circuit Diagram

Code of this above Schematic

#include <Servo.h> Servo myServo; const int flexPin = A0; void setup() { myServo.attach(11); } void loop() { int flexValue; int servoPosition; flexValue = analogRead(flexPin); servoPosition = map(flexValue, 800, 900, 0, 180); servoPosition = constrain(servoPosition, 0, 180); myServo.write(servoPosition); delay(20); }
