Reading a SHARP GP2D12/120 Infrared Ranger by BARRAGAN Demonstrates how to connect and read values from a SHARP GP2D12 and GP2D120 family of infrared Ranger sensors. The ranger is connected to analog input pin 0. The value read from the sensor is proportional to the distance to an object or obstacle The value read is printed to the serial monitor int sensorValue; void setup() { Serial.begin(9600); // sets the serial port to 9600 } void loop() { sensorValue = analogRead(0); // read analog input pin 0 Serial.print(sensorValue, DEC); // prints the value read Serial.print(" "); // prints a space betwen the numbers delay(100); // wait 100ms for next reading } Wiring is an open project initiated by Hernando Barragán. It is developed by a small team of volunteers. © Info, Processing © Info
