databot™ is an open book for programmers, power users, inventors, Makers, and more. Learn to go deep with our Deep Geek docs!
databot™ is built on an open hardware / software platform called Arduino. The following technical details are provided for those of you techies out there that want to take control of databot™ at the hardware level and program your own awesome applications. Here you will find:
If you are new to Arduino programming, or Arduino in general, we recommend you go through our free introduction to Arduino that will give you some good background on what it is all about. It also provides some great links for resources for you to get started on your own Arduino programming journey.
One final, and very important note for you geeks before you dive in, the design and voltage regulator is a 3V3 system within databot™. ALL signals and voltage input from third party devices must be 3V3 or converted to 3V3. For those of you who have burned up a component or two, you will know what we are talking about!
Fortunately, there is an easy solution to this challenge, and it is provided by the awesome geeks at Sparkfun, who like hacking just as much we do. Check out their Bi Directional Logic Level Converter and read through the detailed hookup guide to learn more. This converter, combined with the world of sensors out there, should give you many, many possibilities for expanding databot™.
Good luck and have fun!
