H Bridge

Using Pololu's #2130 to control two motors

I'm going to be making a simple 2 wheel robot that can avoid obstacles using a Ping sensor. I will be using an arduino uno, a breadboard, the motor driver, and two dc motors with wheels. I found Pololu's #2130 after someone recommended it. It can control two motors and it connects to a breadboard. How would I program this like I program an Arduino.

theory vs. soldering

Well...my robot is far from being able to be presented.

In fact I try to build/solder some parts on my own, which seems to be more challenging than expected. Actually I´m soldering a h bridge with its controller based on oddbots h bridge - without the current sensing part - and I just hat to face, that it doesnt work. I guess its not due to oddbots design, but to my soldering skills and or adapting to a simple board design, since I solder though-hole.

I hope I can figure out the problem soon...

question on a h-bridge circuit I found on this page

Hello everyone,

well, I´m pretty new to this community and I hope this post is not too dumb in your eyes. I´m more at home when it comes to computers but as soon as I get into contact with circuits and means to make a computer sense the "real world", I thought about giving it the opportunity to drive around next to other actions. In fact I´m trying my best to deal with microcontrollers and learn by doing.

Actually serving as a test platform to get some programming done and check out all the components I got what to do with them. First cntact with a H bridge since I am using gear motors and no servos.

Hybrid H bridge single relay configuration

So I have been brainstorming H-bridge designs for a 5V motor with 5A stall current.  I want max speed from the motor off 4xAA batteries, so I am considering using a high side relay vs a high side transistor.  I would like the H bridge to:

H bridge using xor gate?

Would this work as an non-smokable h bridge? look in attatchment

p.s how do i put pictures IN my post not attached?
