Hello people, Bob Blick have a very interesting circuit in his page. You could see it on http://www.bobblick.com/bob/projects/hbridge/index.html. It does seem a bit complex to me. There's a simple way to do this? My only problem right now seens to be in controlling a 12V (9V, 24V possible) with logic levels.
