I found this simple freeform design using 3906 and 3904 transistors. would this be a good thing to use on arduino boards?
I have tested it using the blink program tapping the high signal from pin13 (to save time) and tried it on both directions, seems to work ok
this is a more clearer diagram
both link and image are from http://www.beam-online.com/Robots/Circuits/circuits.html
how can i drive servos from this? if i can that is. i know i would need one of these for each DC motor i use.
