OK, so you’ve bought one of the Arduino boards, downloaded some development software, and figured out how to talk to the Arduino to do simple tasks. Now you want to introduce Arduino to the outside world, so you’ll have to learn something about electronics in order to keep that “magic smoke” (more like the odoriferous black cloud of doom!) from escaping from your new little workhorse.
The easiest way to get the Arduino practicing safe outside world contact is to use one of the many “shields” that are available. These are circuit boards which are especially created to interface the Arduino and plug right on to the Arduino board. [click to continue…]
As a computer scientist turned electronics hobbyist trying to fill the gaps in my knowledge of electronics, I find myself visiting the electronics forum over at EEWeb quite a lot these days. (I am a lurker not yet ready for my de-lurking move, though). They are a community of EEs eager to help others, sharing tons of online resources, news, projects and general electronics expertise. Whether you don’t know what a microcontroller is, or are looking for an affordable used oscilloscope on eBay, you are sure to benefit from the information on their forums.
