Hi Brad! I have ordered these, but it shows that it's only green dot , is it normal? maybe it's the connection?..
i have perfectly followed the schematic on the great race??

thanks!

10pcs 8x8 Dot-Matrix 3mm dia. Bicolor LED Display (LE-MM103)

No they are the Bicolour ones, so I would double check your connections?. But note that the Great Race schematic only uses the lower Red Row of LEDs.
