Step 14Insert the Motor controller
Now insert the L293D motor-controller in the last socket. Be sure to turn this one the right way just as the Microcontroller.
The L293D motor-controller will take 4 of the outputs from the microcontroller, and turn them into 2. Sounds silly? Well.. Any ordinary output from the microcontroller can only be on or off . So just using these would (example) only make your robot able to drive forward or stop. Not reverse! That may come in unhandy when facing a wall.
The board is made so smart that the 2 (now reversible) outputs get their own space, marked (A) and (B) just next to the motor-controller (Bottom right on the picture). More about this later.
