Before learning motor interfacing, first, let’s see types of Motors. In electronics, there are three types of motor:
DC Motor : A direct current or DC motor, converts electrical energy into mechanical energy. There are two types of it -
Servo Motor : A servo motor is a rotary actuator or an engine that allows for precise control in terms of theangular position, acceleration, and velocity. It has specific capabilities that a regular motor does not have. Consequently, it makes use of a traditional motor and pairs it with a sensor for position feedback. It has two types:
Stepper Motor : A stepper motor is a special type of electric motor that moves in increments, or steps, rather than turning smoothly as a conventional motor does. The size of the increment is measured in degrees and can vary depending on the application. Typical increments are 0.9 or 1.8 degrees, with 400 or 200 increments thus representing a full circle. The speed of the motor is determined by the time delay between each incremental movement.
Now, the detail explanation of the DC motor is given in the video. The video includes a description of its parts and operation. Also, L293D motor driver, IC demonstration is given. You can learn how to interface DC motor in Arduino. In this, how you can interface more than one motor is also described. Every input/output, voltage, ground etc. pins are explained well.
