The Carrier Trolly


To make a trolly that is able to carry the goods, we can program in the MakeCode editor to give commands such as lifting/putting down the arms, moving forward and stopping driving.

In next course we will make some improvements for an easier operation.

Press button A to lift the arms.

Press button B to put the arms down.

Press button A+B to drive forward.

If taking up the trolly, the micro:bit’s front side would face downward, then the trolly stops driving.
