Analog Input using Arduino

In this blog, I will show you how to create an analog input using Arduino.

analog input

Components required

  • Arduino UNO
  • Potentiometer

Arduino UNO

Arduino is an opensource electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor , a finger on a button , or a twitter message - and turn it into an output - activating a motor , turning on a LED , publishing something online. To do so use the Arduino programming language (based on wiring) and the Arduino Software (IDE) based on processing.

Potentiometer

A three-terminal resistor with a sliding or revolving contact that creates a variable voltage divider is called a potentiometer. It functions as a variable resistor or rheostat if only the wiper and one end of the connector are used.

Code

int sensorPin = A0;    // select the input pin for the potentiometerint ledPin = 13;      int sensorValue = 0;  void setup() {pinMode(ledPin, OUTPUT);}void loop() {  sensorValue = analogRead(sensorPin);  digitalWrite(ledPin, HIGH);  delay(sensorValue);  digitalWrite(ledPin, LOW);  delay(sensorValue);}
