Product Description

A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases.The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on the inside of bend). The connector is 0.1" spaced and breadboard friendly.

These 2.2" Flex Sensors can be easily integrated to an Arduino or Raspberry Pi by making a voltage divider circuit using a *0 K Ohm resistor at any one lead of the sensor.

Use the following Code to integrate a Flex Sensor with an Arduino

//Constants:
const int ledPin = 3; //pin 3 has PWM funtion
const int flexPin = A0; //pin A0 to read analog

//Variables:
int value; //save analog value


void setup()

{
pinMode(ledPin, OUTPUT); //Set pin 3 as 'output'
Serial.begin(***0); //Begin serial communication
}

void loop(){

value = analogRead(flexPin); //Read and save analog value from potentiometer
Serial.println(value); //Print value
value = map(value, **0, **0, 0, **5);//Map value *****3 to ****5 (PWM)
analogWrite(ledPin, value); //Send PWM value to led
delay(**0); //Small delay
