I am trying to automate my rc car for different courses. I want to use a microcontroller to log data that remembers the movement from my rc receiver and save it to an sd card. I would then like to come back and have the car run straight from the sdcard. That way I can have different sd cards for different tracks. Is it possible to do this. I have been using an audrino board to practice programming and an sdcard shield for it. Is there any additional hardware I would need for this project and what would be a good starting point.
