Basic Code:

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 SwitchValue= analogRead(A0);

  // print out the value you read:

  Serial.println(sensorValue);

if(SwitchValue >80 && SwitchValue<120){ Serial.println("Button 1 pressed"); }

if(SwitchValue >130 && SwitchValue<170){ Serial.println("Button 2 pressed"); }

  delay(1);  // delay in between reads for stability

}
