Hi, This is in response to the question about motor voltages posted earlier tonight. Check out the archives. Late last week I posted a similar question and got some good responses about wiring the HB for two power supplies and using diodes. I have (...)

Hmmm. What voltage and/or LEDs are you using? Assuming 5V, your LEDs age passing only around half a milliamp of current. I am using a 100ma LED and I can only get less than a foot of detection. Am I missing something here? Jun Nolasco (...) (28 years ago, 1-Mar-97, to lugnet.robotics.handyboard)

(...) Those are the IR LED's - the one's that transmit the IR light that the receiver sees. Also, while I'm at it, I found out that the diagram above isn't completely accurate (I drew it from memory). The circuit I really use is like this: (...)

(...) The text of your question suggests many possible answers, but I would like to propose a couple of exploratory questions. More importantly it would be useful to have some global state as to what it was you were trying to do. Anyway, you can't (...) (28 years ago, 28-Feb-97, to lugnet.robotics.handyboard)
