Sensing the Resistance new engineering project

In this example the input analog signal is resistance. The circuit arrangement is given below.
As shown, the center pin of POT is connected to analog pin-0. Other two terminals are connected to 5V supply and ground. Digital port pin-13 is having in-build LED.


int sense_pin = A0;    // Select the input pin for the potentiometer
int led_pin = 13;      // Select the pin for the LED
int sensor_value = 0;  // Variable to store the value coming from the sensor

void setup()
{
  pinMode(led_pin, OUTPUT);  // Declare the led_pin as an OUTPUT
}

void loop()
{
  sensor_value = analogRead(sense_pin);  // Read the value from the sensor
  digitalWrite(led_pin, HIGH);    // Turn ON the led_pin
  delay(sensor_value);    // Stop the program for milliseconds
  digitalWrite(led_pin, LOW);   // Turn OFF the led_pin
  delay(sensor_value);   // Stop the program for milliseconds
}
