custom line follower problems[one IR led, is bright, the other two are dim]
April 6, 2010
Hi, i learned eagle basics, so as a first eagle project i made this line follower with sparkfun's QRD1114 IR detector thing.
the project is attached.
what could be wrong here?
from left to right the first QRD is dim, the middle one is bright, the last one is dimmer then the bright one, but brighter than the dim one :S
