Kind of an old topic but I am strying to build one of these. Has anyone built one succesfully? I have a couple of very basic questions and was hoping someone could push me down the right path.
I have all the parts now. Starting in the upper right, when looking at the wiring diagram (from the back) it shows I need GND and 5v. Piece of cake with the bread board.
Then the first wire says it goes from the 7 segment display to D49. Then what? Doesn’t something have to connect to D49 other than the LED?
Does anyone have photos, a better wiring diagram or suggestions?
THANKS
