Hello I recently got my 2yoa21 sharp IR range finder but so far have been unable to return any accurate readings.I have tried many different bits of code , although all amount to the same. I have followed this tutorial to the letter ( i think) http://communityofrobots.com/tutorial/kawal/how-use-sharp-ir-sensor-arduino.
and yet in My serial monitor I see a string of numbers varying between 280 and 300 ish regardless of objects being moved toward or away from the sensor. I have also checked my A0 pin on my leonardo with a potentiometer and it is working fine , does any one have any clues as to what the issue could be.
One explanation could be my wiring: the three wires coming from my range finder are respectively wound round the ends of three jumper wires (but not soldered) which I then insert into the various ports.
here is the code from the tutorial
int sensorpin = 0; // analog pin used to connect the sharp sensor
int val = 0; // variable to store the values from sensor(initially zero)
Serial.begin(9600); // starts the serial monitor
val = analogRead(sensorpin); // reads the value of the sharp sensor
Serial.println(val); // prints the value of the sensor to the serial monitor
delay(300); // wait for this much time before printing next value
