Topic: int sensorValue = analogRead(A0); (Read 3508 times) previous topic - next topic


hello everybody , my potentiometer give values from 0-1023 , and i wanted to the value to  be duplicated  , i can duplicate the the printed value but i wanted the sensor value to be  duplicated, here i attached the code .

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A0);
  // print out the value you read:
  delay(1);        // delay in between reads for stability


i wanted the sensor value to be  duplicated
Do you mean that you want it to be doubled or maybe printed twice ?

Code: [Select]
int sensorValue = analogRead(A0) * 2;

If you like more control over the resulting value, have a look on the Map() method.



thanks everybody for reply thanks again to thomai ,that the answer of my question it works fine
