Lesson 48: Introduction to DC Motors

Lesson 48: Introduction to DC Motors

This project guide provides a comprehensive introduction to DC motors and how to control them using an Arduino. Understanding DC motors is crucial for numerous DIY electronics projects. The ability to control the speed and direction of a motor opens up a world of possibilities. Here are some project ideas you can build once you master this fundamental skill:

A motorized robotic arm for automated tasks.
A small, Arduino-controlled vehicle.
A motorized camera mount for time-lapse photography.
A fan control system for temperature regulation.

This guide will cover the essential aspects of DC motor control, from understanding the different types of DC motors to selecting appropriate drivers and implementing the control logic using an Arduino.

Hardware/Components

To follow this guide, you will need the following components (in video at 00:41):

Arduino Board (any model will do)
DC Motor
Motor Driver (e.g., L293D, L298N) (in video at 11:07)
Connecting wires
Power supply (for the motor and Arduino)

The specific motor and driver you choose will depend on the application and the motor's power requirements. Always refer to the motor's datasheet (in video at 04:08) for detailed specifications such as operating voltage, current draw, and speed.
