I have managed to connect arduino uno board to race coordinator for lap count and timing also the 5 start lights. My question is when the race is paused 1,3 and 5 lights come on and because i am unable to find tri coloured 10mm l.e.d.s they shine red, so can the command be changed to light up 6th amber l.e.d cancelling out the three that light up now. I think it may work because there is a pin available not being used
