Poor Man's H-Bridge
September 25, 2008
So i've just started getting into electronics for the purposes of robots and the learning experience.
Last night i manually built a H-Bridge using 4 transistors in a layout exactly like the one pictured here:
I then used the arduino to control the 4 transistors turning them on and off two at a time to redirect current through the motor different directions.
I was just wondering what other things i should look out for in a real cicuit to do this, protection diodes ?
Any pointers etc. ?
