Great Ultrasound Detector for the Microbit!
This ultrasonic sensor works really well with the BBC microbit. I found a useful example code written in Python for the sensor and Microbit and was able to set the sensor up to take distance measurements. It needs a 5V power source but I found x3 AA batteries worked. The sensor output to the Microbit comes out at 5V so I think it requires a resistor voltage divider to bring it down to 3V for the Microbit.
