RGBDuino UNO and RGBDuino RGB Shield: Add Light and Questionable Arduino PCB
Now, from my writing experience here at eLab, I have dealt with some funny and interesting concepts, but nothing quite like what I am about to show you. But bear with me here, aside from the questionably looking electronics you are about to glance, there might be something useful to...
