How to speed up the dc motor via BS2?
presently, i build a small surveillance robot with use of parallax basic stamp 2 microcontroller, when i plug my dc motor to it, i found that not enough faster the rotation of motor, got any idea to boost it up?
i suppose to modify the programming or add on a additional circuit?

·· How is it you're connecting the motor to the BASIC Stamp?

Thanks, Parallax!
Please do not run this in this configuration any longer!· Also, you aren't giving 6V out of the BASIC Stamp if you're putting 6V into it.· It's a 5V unit, so it's outputs are 5V, but at no more than 25 mA.· You will need a transistor to drive you motor at the very least!

Thanks, Parallax!
As with all H-bridges of this type, it is very important that R and L do not BOTH go high at the same time.
Doing so will let the smoke out of your H-Bridge. You can easily prevent this "accidental" situation with a
simple Opto-isolator configuration that I mention in the link below.
