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>
