Hi Lance,
your project is pure inspiration. On your site you make the statement:
- "What is Lefebure.com GPS? This is a project to build an auto-steer system for agricultural use. More specifically, the system uses GPS data to create a coverage map, and also to steer the machine. The original goal was to build a system that is more intuitive and less expensive than anything else on the market."
The line I've underlined shows that you've achieved your goal. And to think this is your 1st Arduino project!. Amazing.
It really show cases what Arduino is capable of.
