SunFounder Children Electronics Toys Robotics Kits Compatible with Arduino (Ultrasonic Learning kit)

In this kit, an Ultrasonic Sensor Module is included. This sensor works by sending a sound wave out and calculating the time it takes for the sound wave to get back to the ultrasonic sensor. By doing this, it can tell us how far the object is away from the sensor. Apart from some basic experiments, more interesting and complicated ones are provided in this kit applying this sensor.
Code, Fritzing files and datasheets are free to view and download under the LEARN section on SunFounder website.
