5. Motion check

5.1 Let's walk the PLEN:bit!

1. Press A Button to check if PLEN:bit walks.

2. Enjoy PLEN:bit!

3. if can't walk PLEN:bit...

4. Plug in the USB cable into PLEN:bit and your computer. A new drive

will appear in your ﬁle explorer.

5. When you download the ﬁles they may be downloaded directly to your

computer as a .hex ﬁle. Simply move these ﬁles into the new
PLEN:bit drive that was created when it was plugged in and they will
be uploaded into the micro:bit.

5.2 How to adjust ServoMotor position

1. Download this program

https://makecode.microbit.org/_3crgeTemLVUY

2. Push A to start correction

3. Push A or B to move each servo

4. Push A+B to switch to next servo

5. Loop

6. Ends when smile is displayed

7. Reset, then Push B to walk. If PLEN does not fall over, setting is

complete
