Mini Bot Ultrasonic Sensor

The PiBotZero has a dedicated connector for an external ultrasonic or laser range finder. The connector is pin-compatible with the popular and low cost (often for ​less than $1) HC-SR04 ultrasonic rangefinder module and this is recommended. The PiBot Image libraries include support for the HC-SR04 using an Ultrasonic class that is compatible with the WPILib Ultrasonic class.
