<DIV>Yep. That helps. I was actually thinking of a tutorial (I think
Jim Brown did it) on how to trace the H-bridge and find the inputs. But,
as it turns out, I did OK even with my limited analog <shudder> knowledge
(see reply to Dave Grubb).</DIV>
<DIV> </DIV>
<DIV>Looks like I need to ramp up the micro development. Next week.
This one is filled up Wed-Sat. so mad scientist playtime starts Sept
3!</DIV>

hacking</DIV>
<DIV><BR></DIV><!-- Converted from text/rtf format -->
<DIV>Once upon a time I seem to recall a "how to" article to
connect a microcontroller to a toy's H-bridge.
Does anyone recall that or is that a case-by-case only activity requiring a
mentor of the EE persuasion. I'm a software guy with
enough digital electrical knowledge to be a danger to myself and anyone
else near my experiments. So as soon as you talk analog
stuff (capacitors and transistors) I am quickly out of it. I can
recognize them. I can read a datasheet (I look at the pictures to know
which pin is which). And I can sorta trace the lines on a PCB, but do
NOT ask me to generate a schematic. (it usually looks like the PCB, so why
go thru the trouble?)</DIV>
<DIV> </DIV>
<DIV>I have a few moving toys with H-bridges and I would like to connect up
to them and control them with various microprocessors and sensors.</DIV>
<DIV> </DIV>
<DIV>Any guru EE types out there? Or can you suggest a place to
go (URL, not The Hot Place)?</DIV>
