Hi,
I have 2 motors(1.5-3v) hooked up to 2 SN754410 motor drivers(1 motor on each SN754410). I attached both drivers on a breadboard and hooked them up so that they share the same power supply of 6v( 4 AA batteries) At first, they worked, but suddenly they stopped working. One motor does not work completely while the other motor only works for 1 or 2 seconds(supposed to work for 10 seconds). Is there something wrong with my power supply because my motors go really fast.And should I get some type of equipment like a voltmeter?

So have you checked the battery voltage? It could just be that you have drained them. Working for just a few seconds and then stopping sounds like it to me.

A multimeter is very handy. Lets you check voltage, current and resistance, and thus continuity.

Also can we please see your code.

Oh, thanks guys,the battery was just drained. Also, if I want to use 3 motors, should I keep the 6v power supply(because the motors go really fast...its freaking me out a bit.)?
