I received my pre build rainbowduino today. Got everything up and running but 4 LEDs do have som glitches (the blue color wont work unless some pressure is made at the board). As mentioned this does only affect the blue color and the leds:
Z=2 Y=0 X=2
z=2 Y=0 X=0
Z=2 Y=2 Y=2
Z=2 Y=2 X=0
Where should I seek on the construction to find the fault? (I guess I could spend some time on the schematic to figure this out but since it was pre assebled Im to dissapointed that it is some problem at this moment )
Hope anyone here might have a clue!
