1.5 - 3 Volt Motor Control

animadver

Hi everyone,

I have a quick question. I need to control to basic 1.5 - 3.0 V motors. I do not need to control the speed as much as the direction. What is the best way to do this. Am I correct by thinking that since the BS2sx outputs 5V, I would need to regulate the voltage to 3V and also increase the current to match the current needed by the motor? Does anyone have a quick and dirty solution to this with using common parts that can be found at Radio Shack?

Thank you in advance!

The outputs of the BS2 are very limited in the current they can supply. You need to make a simple "H-bridge" switching circuit to control an external supply for the motors. This thread <http://forums.parallax.com/forums/default.aspx?f=5&m=134262&gt; has some specific suggestions.

Thanks so much. I ordered the some parts and I am going to try it out.

I will post my schematic and such after it is all done.

Thanks!
