Thanks for the feedback, gang. You say RadioShack had photodiodes, but
all I've seen are "phototransistors". Is this the same thing? I mean,
they both have two leads, right?
Is there a difference between photodiodes and phototransistors?
What about all these IR receiver modules (Sharp GP1u5X or something like
that)I have?
Jonathan
