Motor CalculationsHey Wade,

Bob Jordan had a tutorial on the SRS Encoder about hacking a toys h-bridges, check it out here :

  Subject: [DPRG] toy H-bridge hacking

  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?)

  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.

  Any guru EE types out there?  Or can you suggest a place to go  (URL, not The Hot Place)?
