Getting your STEM skills up to speed is now easier than ever with Microduino's mCookie. These Arduino-compatible electronics kits make building mini machines a snap -- literally -- with magnetic connectors and interlocking pins that match up with LEGO blocks. The mCookie family of DIY modules, sensors and accessories was Kickstarted back in 2015 and began shipping to consumers at the end of the year. Now anyone can pick up one of the various kits (Basic, Advanced or Expert) and assemble projects like a music box, voice-activated camera, paw-waving fortune cat and more. Microduino also offers additional components to expand the possibilities to keep pace with your imagination. This week, one lucky reader will win a Family Kit (including all three mCookie sets) to launch their smart-machine-making career. Just head down to the Rafflecopter widget below for up to three chances at winning.

Winner: Congratulations to Robin B. of Chico, CA!
