Now, I recieved two good answers for my problems.
1) Built an H-Bridge
2) Use the LMD18200
Now has any one any documentation on an easy H bridge that I could build
without wasting much time?
The same goes for the LMD18200, I understand that is not compatible with
the HB, has any one built a small circuit which would interface the HB
and LMD18200
Oh yeah, one more thing, how about connecting a 5 ohm resistor in series
with a DC motor and there are 2 amps flowing, then the resistor is
dissipating 20 watts of heat.
Now I could have a higher value for the resistor, like 7, 10 ohms, I
think that could do it too!
Is this an easier way???
HAS ANY ONE USED MOTORS RATED OVER 1 AMP WITH THE HANDY BOARD?

| (...) www.yahoo.com, search for "H Bridge", trust me, lots of hits will comeup. Look for the 4QD pages, they talk a lot about H Bridge designs. If you aren't comfortable with electronic design, don't bother though... (...) This IS an H Bridge. Its a (...) (25 years ago, 23-Sep-99, to lugnet.robotics.handyboard)

| Dear Paul, I have an H-bridge that I designed to run big motors. It runs at two amps continuous, and three amps intermittantly. It uses 5 volts for logic from your Handyboard, and 12 volts from a gel cell to run the motors. It also has an analog (...) (25 years ago, 23-Sep-99, to lugnet.robotics.handyboard)
