13. Interface the line-following module to the FPGA-bot, and design a state machine that follows a line. The line-following module has three sensor signals, left, center, and right. If the line drifts to the left, turn right, and if the line drifts to the right, turn left.

Adjust turn constants so that the FPGA-bot moves along the line as fast as possible.

If speed control was developed for the FPGA-bot as suggested in earlier problems, try using speed control for smaller less abrupt turns.
