L293d Motor Driver Pdf
L293D Motor Driver Why do we use l293d?Hey, Welcome to the make it much tutorials point.It’s the 4th one in the series of Arduino Learn by Doing projects series.So Today we will learn about how to use a motor Shield with Arduino. How to drive the motor with the motor driver.And How to use L293d motor driver module/shield with Arduino.I have used this shield for making a remote control robot that I will show to at the end.We can easily control 4 motors with this driver module.Before moving towards the detailed study and use about l293d Module read these posts about:Contents:. L293D is a Motor driver IC used to control motors with a microcontroller. This motor shield consists of three IC’s.
We can control 4 motors with the shield so there are two L293d Ic’s used. The motor shield is used for (Arduino Uno) board.This shield can control servo’s, Dc motors and stepper motors.The two chips of L293D can control four motors with 0.6 A per bridge. The best thing about the shield is we don’t need to write the whole function for driving a motor there is a special library for this module.we just recall some commands to run the motor. When you install the library there will be different codes available in the library for controlling motors. Include the desired library in the code.Here is the testing code for DC motors.
The testing code is also available for servo and stepper motors.In the library, we don’t need to define anything everything has already been defined. Just call the function Forward the motor will start working forward.Same for reverse and so on.We can set the speed of the motor using command setSpeed(speed).The speed will be from 0-255.We can also use this command for separated functions.In the testing code, the same speed is set for four motors. RC car with arduinoTest the Code and Connections.If you found any problem using the motor shield then comment below.Using only the Module for driving motor like L298N is rather easier but we need to define each and everything where we connect motor pins on Arduino and which pins are used for Enable to control the speed.Somehow it is easier.Read the Next post on How to make a Remote control Robot/CAR with L293D module.Here is the picture of an upcoming post about Remote control Robot.Comment below if you have any query and Subscribe to our YouTube Channel for Video tutorials.
The L293D is a dedicated module to fit in Arduino UNO R3 Board, and Arduino MEGA, It is actually a motor driver shield that has full featured Arduino Shield can be used to drive 2 to 6 DC motor and 4 wire Stepper motor and it has 2 set of pins to drive a SERVO.L203D is a monolithic integrated that has a feature to adopt high voltage, high current at four channel motor driver designed to accept load such as relays solenoids, DC Motors and Stepper Motors and switching power transistor. To simplify to use as two bridges on each pair of channels and equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included.The device is suitable for use in switching applications at frequencies up to 5kHz. The L293D is assembled in a 16 lead plastic package which has 4 center pins connected together and used for heat sinking.
The L293DD is assembled in a 20 lead surface mount which has 8 center pins connected together and used for heat shrinking.L294D Shield Feature:. Control up to 4 DC motors.
Control 2 Servos. Logic Control Voltage VSS: 4.5 5.5 V. Motor Supply Voltage VSS: 15v. Drive operating current IO: 1.2A.
L293d Wiki
8 Stage Serial Shift RegistersWiring a DC MotorMotor requires more energy specially cheap motors since chip motors less efficient. The important thing you need is find out what voltage require your going to use.
Some small motors are only intended to run at 1.5 volts but it is just a common to have 6 12v motors. The motor controller on L294D shield is design to run at 4.5v to 25v. Most 1.5 3 volts motor will not works on this shield. Another thing you need is to figure it out how much current the motor will support? The L293D chip support up to 600 mA per motor, with 1.2A peak current.

Note ones you head towards 1A you’ll probably want to put a heat sink on the chip, otherwise it will get thermal failure or burning out the chip.On using the SN754410 motor driver chip because it has pin compatible, has an output diodes and can provide 1A per motor, 2A peak, you can download the datasheet below.If you want more power you need to add a set of L293D driver and solder them right on top of the board it has now a double current capability. You can cannot run motor of a a 9v battery it drain very fast. Use NiMH or Lead ACID or LiPo Batteries it can provide 99% performance of the Motor.Note: Do not connect the motor to 5v line on the board. There are two places you can get your motor high voltage supply.Wiring and Installation the DC Motor to the l293D ShieldThe DC motor are used for all sort of robotics projects.

The motor shield can drive up to 4 or 6 DC motors bi directional, it means that they can be driven forward and backward. The speed can also be varied at 0.5% increments using PWM(Pulse with Modulation) this means that speed can be controlled.Note: The H-Bridge Chip is not supported for driving load over 0.6A over 1.2A so this it means that this chip is for small motors.
