To make the Freetronics site a bit more useful we’ve just started writing up short tutorials on specific Arduino-related topics. The first one is about how to solder headers (both regular and stackable) onto Arduino shields and make sure they go on straight, which can be harder than it sounds. The tutorials section is accessible using the “Tutorials” navigation link on the side of every page on the site.
To start with we’re just going to take some wild guesses about the sorts of things that people may find interesting, but we’re definitely open to suggestions (and maybe even bribes!) so if you want us to write up a specific topic please zap an email at us.
