Ultrasonic (HCSR04) component

This board has both an ultrasonic transmitter and receiver. When the Trig pin is set high for 10uS, the transmitter sends eight 40KHz pulses. The Echo pin goes high about 2ms later. The duration of the Echo pin is measure when it goes high, and a distance is then calculated based on the high duration. The distance of objects in a range of around 3cm to 2.75m can be determined.
