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 possible to amplify the signals the
ir output generates?. If so how?
+ - + -
Grnd <---|-----O------LED-----LED----
| - + - + - + |
<---|------LED----LED-----LED--
O is a 10k pot
3-4 LEDs work great but anymore just kills the signals.
thanks,
phet

| Run them in parallel, use a transistor. Like so: +5v | +---+---+---+---+---+ | | | | | | \ \ \ \ \ \ / R / R / R / R / R / R \ 1 \ 2 \ 3 \ 4 \ 5 \ 6 / / / / / / -- -- -- -- -- -- \/ \/ \/ \/ \/ \/ -- -- -- -- -- -- HB + | | | | | | \ | | | | | | / (...)
