Ultrasonic sensor HC-SR04 - Arduino due

Ultrasonic Sensor HC-SR04 is a distance measuring sensor. The sensor has one receiver and one transmitter. The transmitter sends a generated soundwave and receiver receives reflected ultrasound. The ultrasound was emitted at 40 kHz, which travels though the air, if there is a barrier on its way, it will bounce back to the module. By using travelling time and the velocity of the sound, distance can be determined. Sensor consists of 4 pins: VCC, TRIG, ECHO and GND. The supply voltage is connected to VCC pin, which is +3.3V. TRIG and ECHO pins can be attached to any Digital pins in Arduino Board.

You could make the LED flash at different speeds based on the measured distance.
