### Micro:bit Radio Channels Designation

In order for the Micro:bits to work as intended, they need to be set to the correct channels.

The Radio channels can be set in this programming block.

### Troubleshooting

#### Q: The Robot Arm is unstable and shaking when moving.

#### A: The battery has run out, charge the battery with a USB cable.

#### Q: The Robot Arm cannot grab onto objects.

#### A: Try using a soft object to increase grip, or try lighter objects.
