I have a c++ program written for an arduino leonardo that works fine on my new Raspberry Pi b3. The signals from a ColorPal 28380 color scanner go to pin 9 of the arduino. The program's "if" statements command various segments of a 7-segment LED to form a different multi-segment digit for each of ten different colors that are scanned by the ColorPal.

I need to modify the program so that a projector which is connected to the HDMI port of the RasPi will display a different BMP digit image for each of the "if" statements when each of the ten colors are scanned by the ColorPal.

Other work on this extended project will be required, if I can hook up with the right programmer.
