Controlling DC Motors With the L298N H Bridge and Arduino

Learn how to control DC motors using the L298N H-Bridge Motor Controller and Arduino in this comprehensive 37-minute video tutorial. Explore the history and functionality of DC motors, understand H-Bridge circuits, and master Pulse Width Modulation (PWM) for speed control. Connect the L298N module to motors and an Arduino, then progress through three practical sketches: a motor control demo, dual potentiometer speed control, and joystick-driven motor control. Apply your new skills to build a simple Arduino-powered robot car, gaining valuable insights for future robotics and IoT projects.
