Things used in this project

Hardware components

BBC micro:bit board

NeoPixel Ring: WS2812 5050 RGB LED
Adafruit NeoPixel Ring: WS2812 5050 RGB LED
I used a NeoPixel 12 LEDs ring

Kitronik All-in-one Robotic Board
As I started to test the feature of this board I was very impressed! It can control up to four DC motors (or two stepper motors) AND up to 8 servos, with an independent power source to the external devices while powering the BBC micro:bit. One of the most interesting aspects of this expansion board, IMHO, is communicating to the micro:bit via I2C. In few words, after you have connected all the stuff for your robotic project the micro:bit has already all the available GPIO pins free. I found this invaluable for this project.

Software apps and online services

BBC micro:bit blocks
The software has been written with Javascript compatibles with the online Blocks editor offered to program the BBC micro:bit board from the microbit.org site

Hand tools and fabrication machines

Eleksmaker laser engraver and cutter
To cut the cardboard and some other parts I have used the Eleksmaker A5 model with a 2500 mW blue laser
Dremel hot glue gun
Elegoo MARS LCD resin 3D printer
