During the past couple of years, an entire ecosystem has grown around the BBC micro:bit board. Today, a wide choice of educational kits based on that microcontroller platform is available on the market. I will be presenting readers with a different project every issue, exploring the available kits for the BBC micro:bit, their features, and possibilities.
This issue’s project is based on the Kitronik Inventor’s Kit (kitronik. co.uk/5603-inventors-kit-for-the-bbcmicrobit.html) used to create a wind machine, with the valuable collaboration of Xavi, a young enthusiast maker. Kitronik’s kit includes a considerable variety of components from which to create many different electronic projects. From resistors to capacitors and LEDs, to transistors, and more, the box contains all that is needed for a basic electronics course. The only detail that I found was missing is a servomotor with the included DC motor.
Power of the wind
The wind machine is a scale model of a wind generator. This will go some way to helping you understand in practice how the ‘green’ wind force can be converted into energy through a generator, in
