| | | Hi, I'm trying to get the ir output on the handy board to power more than 4 LEDs (need to power 6), anything beyond that the ir signals become drastically weak. I have these LEDs wired serially. I'm not too familiar with electronics, so is it (...) (27 years ago, 5-Aug-97, to lugnet.robotics.handyboard)

| | | | No, don't use a transistor! The HB's IR out already has one. But the parallel-with-a-sepa...r-for-each method is correct. -Fred In your message you said: (...) (27 years ago, 5-Aug-97, to lugnet.robotics.handyboard)
