Working With A Hbridge Driver and Optocoupler

A USB integrated development environment
I'm excited to start learning how to effectively use a h-bridge driver and Optocoupler. I created the breakout boards pictured in the bottom of the image last Monday at work and got my development environment set back up and running on a breadboard. The components I use in my development environment are as follows.

1.An FTDI FT232RL for easy USB communication to the computer
2.An Atmel ATMEGA 8L running at 8mhz programmed by a direct home-made parallel cable programmer

Both of these components and associated LED's etc, don't require much amperage so they can all be powered off the USB bus power. The optocoupler is a commonly found Fairchild 4N25 and the bridge driver is a Freescale 33883. A high note of this project already is that I had zero problems with making the breakout boards and the surface mount soldering. When I checked all the pins I had no bridges and good continuity between all the pads and pins.
