Ultrasonic Distance Sensor for Bit:Bot Classic

NB. Bit:Bot not included

 Ready-Soldered, just attach to your Bit:Bot with the screws provided and off you go.

 Use Microsoft PXT (or MicroPython with some awkward code) to read the distance to an obstacle, then program your Bit:Bot to avoid it.

Both Ping and Echo signals are on the same pin (Pin 15)

The sensor soldered into the PCB is much more robust and reliable, but has a big drawback in that you cannot access the micro-USB connector on the micro:bit unless you either remove the micro:bit or use a right-angled USB cable.

 Consider using the right-angled USB cable with this option
