Remotely control TI-Rover direction, speed and turn radius via the two IN1/IN2 analog input ports.Project includes the full documentation, schematics & code. Code includes a stick calibration program to virtually support any type of analog input sensor such as the the ADXL335 accelerometer or the TI-Vernier accelerometer to control Rover and the main() program as the control loop. Key mathematic element is a map() function which scales values of a given input range into to values of a different output range, as long as the relationship between the two is linear.
