Hi all.

In my class today my students are not able to get the Maqueen Ultrasonic to work.

All they can get is 0 to display on the LED.

I notice in the github repository there was a change related to the ultrasonic 4 days ago.

Has this introduced a bug??

Hi, please kindly note that we have tested the full library, the code is alright.
Well, once the ultrosonic exceed 4m, the LED will show 0. And if the Maqueen battery is not turned ON, the mainboard is only powered by USB port will also lead to 0 display.
Please check the inspection range and power supply.
