Robotics - L293D Motor Driver IC

L293D Motor Driver IC

component that controls TT/DC motors, and consist of several pins

TT/DC Motor

a robotic component that is typically used for robot wheels. It comprises of stator, gears, and a shaft.

PWM pins

can produce analog signal with continuous value from 0-255

Digital Pins

Digital signal only, two values which is on and off

VCC 1

powers the logic for the IC and is connected to the arduino. It handles 3V and 5V

VCC 2

powers the external motors. It can attach up to 34V

GND Pins

Allows current, and excess electrons to flow through and provides a common ground for the L293D's internal logic and the motor's power supply.

Enable Pins: 1&2, 3&4

Turn the motors on and off, and can also control motor speed using PWM signals

Input and Output Pins

• manipulates the directions of the motors, whether forward or backward.

• Input: connected to digital pin

• Output: connected to the motors
