Chris,
Did what you said to fix the filtering problem on my BOE. But when I go
to adjust the POT it just reads 0000? And the robot itself jags right, and
barely moves forward. No matter what it come in counter with. What could I
be doing wrong this time? I am kinda new to this, so please bare with me
hear. I know about electronics, but robotics, I am new to. I would again
appreciate your help. -Alex
Also, I just saw your message about finding IR's yourself. Look at
Digikey. Some one else told me about this a day or so ago. They have a wide
range of recievers there. I am sure that you will find what you are looking
for. (and there prices are pretty reasonable to, that is a +) Hope you find
what you want.
