well, I probably should have looked at that before I mounted them....the readings seem to be fine though.......and Paul, sorry about that...I'm a bit lazy with commenting and stuff.....And aren't sonars a lot of money? Do they make cheap ones?
It isn't really a set made course, most likely going to be a local park (with trees) and another test using this algorithm specifically would be inside my high school hallways
And are there any good tutorials on how to get an arduino rc car to work the way I want it to with a GPS?
It does all seem to be flight based that's for sure. But can you define your parameters a bit better, when you say navigate via gps do you mean move from known starting point to a known waypoint ? Or from a known start point to a waypoint that is identified by a system other than gps coordinates ?
