The kit

The Shed - - Bbc Micro:bit -

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 
