what I am doing right now is building a car that goes through a path using 3 ultrasonic sensors and I am storing the values the values the sensors return during the run. I want to use this values on a second car, so essentially the file on the sd card would be the "sensors". Do you think that by running the code that you wrote I will be able to do that?
If you are alluding to what I wrote in #16 and #18 above, then no. It's not code per se, it's just snippets to establish the principle. I'm only talking about storage and I know nothing about robot cars. However, if I understand you correctly, I can't help but agree with the other guy.
Car#1 establishes the course to be steered by feeling its way with sensors.
Car#2 follows the same course without sensors, but using the sensor data from car#1
It would seem more sensible for car#2 to use the mechanical commands that car#1 used to achieve the desired result. That would tell car#2 what to actually do rather than describe the view out the window.
The storage issue is essentially the same - and just as easily solved!
