PiRoConB12DocsThe PiRoCon series of Robot  Controller boards are the most complex of the range by 4Tronix and designed to be used by serious Roboteers.

ScratchGPIO is programmed to use it to control the motors.

Also 2 servos can be controlled if they are connected to pins 18 and 22 and controlled by variables called Pan and Tilt

An ultrasonic module can be plugged in and ScratchGPIO will return distance measurement in cm every 1 sec

Sensors can be connected to pins 7,11,12 and 13 such as IR obstacle Sensors and IR Line sensors
