Lesson 95: Using a L293D 4 DC Motor Shield | Arduino Step-by-Step Course

In this lesson, we learn how to use the L293D Motor Shield to control four DC motors. We learn to control the speed of each motor, change its direction, and start or stop them. Wiring diagrams are shown. The code is fully explained and demonstrated using an Arduino UNO and an Arduino MEGA. This code is for a single sensor.
