Arduino code and video for Voltage Sensor Module Robojax.com

This is the Arduino code and video for Voltage Sensor module

This video shows you how to use Voltage Sensor module and also how to use it to measure any voltage by showing you how to calculate the resistor. http://robojax.com/learn/arduino/

 * This is the Arduino code for  Voltage Sensor
 * you will measure voltage using this module which eliminate use extra resistors
 in the video also you will learn how to measure any voltages.

 * Watch the video instruction for Arduino Voltage sensor https://youtu.be/FaoKzi7tgME

int offset =20;// set the correction offset value
void setup() {
  // Robojax.com voltage sensor

void loop() {
  // Robojax.com voltage sensor
  int volt = analogRead(A0);// read the input
  double voltage = map(volt,0,1023, 0, 2500) + offset;// map 0-1023 to 0-2500 and add correction offset
  voltage /=100;// divide by 100 to get the decimal values
  Serial.print("Voltage: ");
  Serial.print(voltage);//print the voltge
