Custom electronics board tutorial for FOBO

A big thanks to Andy for designing a custom electronics board for FOBO! This combines the parts from the Arudino Uno and the servo shield into one inexpensive board. He went above and beyond by also creating a great tutorial on how to make the board and assemble the components. This will be really helpful to everyone who hasn't been able to get a hold of the discontinued servo shield used in FOBO. Really great work!
