To followup on yesterday’s Intern’s lab project that featured clicker for STM32, today we have a new project, this one utilising clicker 2 for STM32. Additional note: few sentences in Yoda-speak, the description of this project will have.


Can you feel the Force radio waves around you? Here, between you, me, the tree, the rock, everywhere, yes. Even between the mikromedia+ and the clicker 2.

If you can’t, don’t worry, the Nordic nRF24L01P 2.4 GHz transceiver module can.

Always two there are. A master, and an apprentice a slave. The master nRF24LO1P is on the mikromedia+ for STM32. The touch-screen interface on the board allows you to choose to drive the motor clockwise or counter-clockwise, in full-, half-, quarter- and eighth-step modes. The commands are received by the slave module on nRF C click that drives the motor via stepper click.

What you get in the end is Yoda rotating on a makeshift stand made from a piece of discarded foam leftover from some packaging designs (it’s just the usual stuff one finds in a Marketing Department office).

But if you want to reuse this project to make your own special edition, both the master and slave codes are up on Libstock. You could alter the code to enable the mikromedia to control more than one nRF-enabled device for example. Ivan, the intern behind this project, says it’s simple to do.

Yours sincerely,
