Lesson 51: Control 2 DC motors using Arduino and L293D Arduino Step by Step Course 827 views 42 Dislike Share Save Robojax 80.4K subscribers In this lesson we learn how to use. The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM. Similarly, for controlling a second motor B, pin 9 is the Enable Pin, pins 10 and 15 are the control/input pins and Pins 11 and 14 are the output Pins. Interfacing of ARDUINO DUE WITH DC Motors with the help of L293D Motor driver IC.Pin 8 of L293D IC is the supply for driving the motor and is connected to a 12V supply. Pin 16 of L293D IC is the supply pin for internal operations and is connected to a 5V supply. L293D Motor Driver IC needs two types of power: one for its internal operations and other for driver channels that drive the motor. Hello all, I plan on running two 12V DC gear motors as well as some IR sensors and ultrasonic sensors off of a Ruggeduino and a SainSmart L293D motor shield. The remaining connections with respect to L293D IC are the power supply pins.Pins 4, 5, 12 and 13 of the L293D IC are ground pins.They must be connected to the motor we are going to control. Pins 3 and 6 of L293D are the output pins of first driver channel.They are connected to Arduino Pins, Commonly PWM Pins in Arduino are used. Pins 2 and 7 of L293D are input / control pins of driver associated with motor A.This makes it useful for using a PWM output to control the motor speed. If you move Pin 1 (Enable) to GND the motor will stop, no matter what you do with the control/input pins. It is an active high pin and hence it is connected to 5V supply. Pin 1 of L293D IC is used to enable the driver channels 1 and 2 i.e.L293D is a 16-pin IC available in dual in-line package. L293D IC is designed to drive relays, DC motors, stepper motors and other inductive loads with high current and high voltage requirements. It can be used to drive two motors at a time in both the directions with an output current of 600mA for each motor. L293D is a quadruple H-bridge, high current motor driver IC. ![]() These usually require a few extra components (a few resistors, a capacitor, and a +5v power supply from Arduino) but take care of the motor-control. The term motor-controller refers to an amplifier that is designed to control the speed and direction of a motor using a specified set of signal commands.Ī motor-controller IC is an integrated circuit chip that is designed to use a low-power input signal to provide a high-power output signal commanding both speed and direction to a DC motor. ![]()
