How to give your Arduino robot eyes!… (Ultrasonic’s really!)

HCSR04_CloseupWhat robotics project doesn’t need eyes? By eyes we’re referring to HC-SR04 Ultrasonic Sensors. We have put together a quick and easy library to get started with using these sensors.

The HC-SR04 is a low cost, easy to use sensor that will measure distance by bouncing ultrasonic sound waves off of obstacles in front of it.┬áIdeal applications for the HC-SR04 is using them for obstacle avoidance systems in your robots/RC cars – This will be quite short post as there isn’t much to it.
