PBP projects for R/C models

There are plenty of machine cycles to do the math work and the control decisions. I think the 5 millisec interrupt timing should give me accurate timing for the PWM signals. I have no idea how much noise there is in the SONAR responses. I want to space them further apart in time so the trends are clear. Four triggers for each SONAR per second is my first guess.

Now to bed. Thanks.

I think once you have the PWM stuff sorted in your head, I feel like you may need to address this not knowing part. If your car is going a mere 10 mph, that's approx 14 feet per sec. If you only check each direction (front and side) four times a sec, your car will have traveled 3.5 feet!!! Ok maybe you are not going 10, but how bout 2 mph? That will still be 7.5 inches. At that rate, you will be correcting for things long past.
