Codebug, the ex-Kickstarter project, is now on sale at CPC for £15. The small board can be connected up to a Raspberry Pi via USB and used as an input device via a Python library. Thomas Macpherson-Pope has, over on the Codebug site, written a tutorial which shows you how to detect when a circuit is created on the Codebug and then have that trigger, via the picamera library, the use of the Pi Camera. It’s a nice little project that shows you how to use the two devices together. Read the tutorial here.
