Subject: [alt-beam] Re: Advice needed!
look for the notch or flat side of the LED, or just take 2 AAA batteries
and touch it to the leads to find out!!! READ THE BOOK!!!! it's all in there!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
OK! Read the book!! (:
Again, the LEDs will only light then if the Microcore is in single
process state. If the microcore saturates, you won't have any LEDs lit.
Only while it walks. I recomend type A arangemnt (refer to my previous
message) for the microcore, and type B as optional walking indicators. A
lights do the same as B lights, but they show more. the B arangement is
great to reduce wiring on model railroad crossing signal flashers
though!!! 2 wires instead of 3. can be driven by a Microcore too!!! of
course, yyou don't need to know that! (well, maybe! :)
again, read the book first, and THEN ask questions, cause if you read
it, and try to understand it, you can answer most of your questions.
good luck.
you also realize you need a PNC to reduce the microcore from Saturation
to single process, right. I guess you did that, since you said some legs
worked and not others.
