Another H-Bridge Post
February 13, 2010
So, it's my turn for an H-Bridge post.
It's a simple one too - I'm looking for a circuit that I can build without confusing the heck out of myself.
I've gone through about 6-7 different articles (with schematics and the like) about them, and understand the concept behind them. I've even tried to put a few together, but have had zilch in the way of voltage flowing out the other end.
This circuit is the one I've tried three times so far, as it's the only one I can find that specifically uses a breadboard.
I'm still having trouble visualizing all the connections in a schematic to get everything to work properly, so this post helped a lot.
However, I still can't get it to work.
I could break down and buy an L293D, which I will soon, but I'd like to build the bridge from scratch to help me with learning more about circuits.
Anyway, if you know of anything that might help, I'd be greatly appreciative. I'm heavily considering just going back to the beginning and finding a book that will teach me from scratch while putting off the robotics until I get a better handle of electronics.
