Earlier this week I blogged about some of the stuff I’d been doing with Arduino and I mentioned that my code is up on GitHub. What I didn’t mention is how it got there…

I use the Arduino IDE on a netbook running Ubuntu Linux (other development tools are available) and, a few weeks ago, I stumbed across an interesting-sounding hack to store sketches (Arduino code) in the cloud. The tool to make this happen is David Vondle’s Upload and Retrieve Source project. There’s a good description in Dave’s blog post about the project that clears up parts I struggled with (like: the location of the gistCredentials.txt file, used to store your GitHub credentials and which is found in the ~/.arduino folder on my system; and that you also need the username to be included in a comment inside the sketch).  Of course, you’ll need to create an account at GitHub first but you don’t need to know anything about the various git commands to manage source code once you have created the account.

The only downside I’ve found (aside from plain text passwords) is that there is only one project for each Arduino – if you re-use the Arduino with another circuit, the new sketch will be stored in the same gist (although the version control will let you retrieve old sketches, if you know which is which)
