New product: SparkFun Inventor's Kit - V3 (with RedBoard)

The SparkFun Inventor’s Kit has everything you need to construct a variety of circuits that will teach you how to use an Arduino-compatible RedBoard to read sensors, display information on an LCD, drive motors, and more. No previous programming or electronics experience is necessary, which makes this a great way for beginners to get started with embedded systems. The V3 version includes a RedBoard and detailed instructions for building 15 educational circuits with the kit components.

This replaces the older SparkFun Inventor’s Kit for Arduino with Retail Case.

For more information about the SparkFun Inventor’s Kit, see the product page.

Paper ROM and balsa wood airplane

Posted by Jon on 26 August 2013

Customer Mike Kohn recently wrote to us about two of his projects that use Pololu parts:

This paper disk is marked with black and white patterns spread across four distinct rings and can store a total of 16 bytes of data. Mike decodes the data with one of our QTR-1RC reflectance sensors. Read more about “PAPER-ROM”…


This balsa wood airplane uses an ATtiny85 to interpret signals from a Syma S107 helicopter remote controller, and it uses our 5:1 micro metal gearmotor HP to spin its propeller. Read more about this airplane project…

Mike has documented many of his other software and electronics projects on his web site.
