Arduino Ultrasonic Chat Control

Ultrasonic sensors measure distance with ultrasonic waves. It measures timeframe from emitting sound until receiving the rebounced soundwaves. By knowing the soundspeed (340.29m/s), the ultrasonic controller can calculate the distance in 0.01cm accuracy. You can always ask the current distance between any object and the sensor. This a perfect tool for building small robots.

You can chat with the device at the Ozeki 10 as the video shows below.
