Sanki Notes

  • Position (Black : Blue)
  • Black Up : 4700 Ohm to 5V and to Pin A0
  • Blue Up : 100 Ohm to 5V
  • Black and Blue Down to GND 


          This example is Read A) and Range 200 to 950 (1 Inch Around )
  1. /*
      Reads an analog input on pin 0, prints the result to the serial monitor.
      Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
     This example code is in the public domain.

    // 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(100);        // delay in between reads for stability
