4. What is micro:bit?
The BBC micro:bit is a pocket-sized (52 x 42 mm –2” x 1.75”) computer, 70 times smaller and 18 times faster
than the original BBC micro computers used in schools. The design is appealing to a young public. It features
25 red LEDs used to flash messages and create games.
micro:bit is compatible with different coding languages starting from Block Editor and mobile apps for the
starters, to Python for more advanced users.
micro:bit has an accelerometer so it can detect motion and knows when you are on the move. The built-in
compass knows which direction you are heading in and it uses a low-energy wireless connection to interact with
other devices and the Internet.
Each element is completely programmable via easy-to-use software on a dedicated website (microbit.org)
accessible from a PC, tablet or mobile.

VMM500
V. 01 –17/01/2019 13 ©Velleman nv
Once loaded, the Ring:bit Car appears in the code drawer.
7.2 The S-Walk
We make a code to let the Ring:bit Car run in an S-shape.
1. On start, set the pins for the servos.
2. Move forward for 1000 ms.
3. Turn left for 1000 ms.
4. Move forward for 2000 ms.
5. Turn right for 1000 ms.
6. Pause for 1000 ms.
7. Move forward for 1000 ms.
8. Download the programme into micro:bit.

VMM500
V. 01 –17/01/2019 14 ©Velleman nv
Drag and drop the block set left wheel at pin P1 right wheel at pin P2 into the block on start in the editor
window. You will find this block in the Ring:bit Car menu of the code drawer. When correct, they snap together.
Now, make a second block as shown in the image.
Drag and drop the block move forward into the block forever. Then, drag and drop the pause block under
the move forward block. You will find the pause block in the basic menu of the code drawer. Set the pause at
1000 ms (= 1 second).
Now, do the same for the other blocks for steps 3 through 7.
When complete, we compile the program to generate a .hex file. Click on the download button and save the
.hex file to the Downloads folder (C:\downloads). This .hex file is ready to be uploaded to the micro:bit.
Plug the micro:bit into the USB port via the micro-USB cable. Then, drag and drop the .hex-file (from the
Downloads folder) onto the micro:bit Removable device to upload the programme.
Now, place the Ring:bit Car onto the ground and switch on the micro:bit via the on-off switch. The Ring:bit Car
runs in a S-shape line.
7.3 Drawing a circle
We make the Ring:bit Car draw a circle. Install a pen or pencil as shown below and install the Ring:bit Car on a
sheet of A4/A3 paper or cardboard.

1. Set a different speed for the two wheels.
2. Download the programme into micro:bit.
The block left wheel speed (0) right wheel speed (0) can be found when you click on More in the menu of
the code drawer.
When complete, we compile the programme to
generate a .hex file. Click on the download button
and save the .hex file to the Downloads folder
(C:\downloads). This .hex file is ready to be
uploaded to the micro:bit.
Plug the micro:bit into the USB port via the micro-
USB cable. Then, drag and drop the .hex-file (from
the Downloads folder) onto the micro:bit
Removable device to upload the programme.
Now, place the Ring:bit Car on a sheet of A4/A3
paper or cardboard. Switch on the Ring:bit Car and
see what happens!
7.4 Wireless control
Let’s make a remote control for controlling the Ring:bit Car via RF (radio frequency).
For doing that, you will need a second micro:bit in option.
Click button A to turn right.
Click button B to turn left.
Click buttons A + B to move forward.

Then click on the gear icon again, and drag and drop the new created logic function under the forever loop.
Now, place the block button A+B is pressed next to the first if logic. Place block button A is pressed next to
the first else if logic, and block button B is pressed next to the second else if logic. The blocks can be found
in the code drawer menu.
Now, place the radio send number 1 block next to the first then logic and set the number to 1. Drag and
drop a second radio send number 2 block next to the second then logic and set the number to 2. Drag and
drop a third radio send number 3 block next to the third then logic and set the number to 3. Drag and drop a
fourth radio send number 0 block next to the else logic and set the number to 0. The blocks can be found in
the code drawer menu.
Click on the gear icon for more
options. Then, drag and drop the
else if logic in the following
order.

VMM500
V. 01 –17/01/2019 17 ©Velleman nv
