Arduino Self-Driving Car Lesson 3: Controlling Motor Speed

The video tutorial explains how to control the speed of a motor using Arduino by implementing PWM (Pulse Width Modulation). It covers the basics of digital and analog signals, the use of PWM pins, and how to write Arduino code to control motor speed. The tutorial also addresses practical applications, troubleshooting, and advanced techniques for flexible motor control, allowing for independent speed and direction control of motors in a robotic vehicle.

How does the Arduino simulate an analog output using digital pins?

What challenges might arise when trying to control a motor at very low speeds?

In what ways can you modify the drive forward function to allow for variable speeds?

What are the potential applications of being able to control the speed and direction of a robotic vehicle independently?
