MakeKit Air:bit 2 User manual

Teachers! Read this
The Air:bit 2 is a great way to engage the students trough cross curriculumn teaching and learning. Here is some useful information.
Time frame
Building takes 2-3 hours
Coding the remote controller takes 3-4 hours or you can download the readymade code.
Flying takes about 30 minutes (flying and adjusting before battery is empty)
We recommend charging the batteries while coding. Charging with Air:bit V2 takes approx. 1 hour.
Micro:bits
We recommend two micro:bits for a drone/transmitter pair. The drone should have micro:bit V2 on board. See the next page.
Radio channels
Each student should select their own radio channel for transmitter and receiver. (0-255). If you use ready made code, make sure to edit the
variable called radioGroup in makecode before downloading to micro:bit (both transmitter and receiver)
Flying
Use an open space close to where you build the drones. A soft carpet is better than a hard surface in case of crashes. A high ceiling is not
needed (in case of crash, high falls are worse)
Read more about flying at the end of the document or see the video at www.makekit.no/docs
Safety
The propellers are small but spins fast and can make small cuts in the skin. Students should be cautious when the propellers and battery are
both connected. If you leave the propellers unmounted until the end, you can test run the motors first.
Repairs
All parts can be replaced. The most wear goes to propellers and motors. Keep some spares at hand or order more from your distributors or
directly from Makekit (sales@makekit.no)

Micro:bit V1 or V2?
V2
The remote control works great on both micro:bit V1 and V2.
Air:bit 2 relies on the micro:bit for high speed calculations and stabilisation. Therefore,
we highly recommend using micro:bit V2 on the drone.

air:bit to fly, please see page 61.

Fast rotation propellers can hurt humans and animals
To prevent injury, do:
•Mount the propellers at after all building and coding is
done. Test that you can start and stop motors (shake to
stop)
•Keep a distance when arming and flying the drone.
•Children under 8 years and animals must be kept at a safe
distance, at least 5 meters away even indoors.
•Use propeller protector if possible
•Follow local FAA regulations
Safety warning
Lithium batteries can release smoke or cause a fire
To prevent damage, do:
•Don’t charge the batteries unattended
•Don’t use a damaged or punctured battery
•Do not short circuit the battery
•Avoid temperatures below -10 and +50 degrees celcius.
•Don’t use batteries that are colder than 15 degrees celcius
•Always have a plan for what to do in case of a fire: If you are
indoor, open a window and get the battery outside to prevent
smoke or fire.
•Do not open or modify the battery in any way.
•For optimal performance, store the battery at around 50%
capacity and between 10 and 20 degrees celcius
•Follow airport regulations for carrying lithium batteries on
airplanes. (Usually hand luggage only)
Watch your fingers -
do not touch the
rotating propellers!

Meet the micro:bit V1
Front Backside
You can learn more at: https://tech.microbit.org/hardware/
micro:bit is a small computer with prosessor, sensors, display and radio. It
has connection pins for external components like LEDs, speakers or various
sensors.

The micro:bit V2
Front Backside
The micro:bit V2 is very similar to V1 but with extra features, like:
Microphone, speaker, touch button, faster processor and more memory.
The “gold teeth” looks different compared to V1, for better grip with
crocodile clips.
Air:bit can work on V1 and V2, but V2 gives more processing power for
advanced users.
