Step 6: What's It Doing.
While working on this project I was given an old fire alarm panel. This panel had a Hitachi LCD display. This display, as I found is one of the most popular types available. So using one of the many examples on-line, I connected it to the Arduino. I use the LCD display to show me what the software is up to, Ie. on-line, power control, forward, backward, etc. I accomplished this using a simple LCD print command at each instruction. I also printed each "direction" to serial output as well.
