This weeks project goes over different Interfaces and the programming possibilities that can be used to interface with something we have already built. Since the RGB device doesn't have any serial input in the original device, we're going to build an interface using the serial RS-232 device since the ability to interact with the device already exists.
Add stuff that would be cool to investigate when time and resources permit.
This article discusses in great detail PCB milling with loads of information on V-engravers.
