Arduino Programming basic Read Analog Voltage

Arduino Programming basic Read Analog Voltage 

Procedure:

Step 1:     Open the Arduino software

Step 2:     Go to file

Step 3:     Then move to examples

Step 4:     Then open Read Analog Voltage program

Step 5:     Then watch the video 

Step 6:     Make clear and brief detail pf this program from this video

 

Step 7:     Try to make implement with Potentiometer

Step 8:     By adjusting Potentiometer Analog voltage values can be varied

Step 9:     By using serial monitor output values can be read.

Video:

Program:

void setup() {

  // initialize serial communication at 9600 bits per second:

  Serial.begin(9600);

}




// the loop routine runs over and over again forever:

void loop() {

  // read the input on analog pin 0:

  int sensorValue = analogRead(A0);

  // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):

  float voltage = sensorValue * (5.0 / 1023.0);

  // print out the value you read:

  Serial.println(voltage);

}
