The direction of rotation of the stepper motor will depend on the sequence in which the electromagnetic coils of the motor are energized and the speed of rotation is determined by how frequent these coils are energized.The motor is going to be connected as shown in the schematic below. L293D can also be used to drive servo motors. This shield offers total fourBefore using the L293D motor driver shield with Arduino IDE, we need to install the This motor shield can drive DC motors having voltages between 4.5 to 25V.

Robot seguidor de línea para arduino + código talos.

Since I am using simple motors rated at about 3 to 9V, the VCC2 pin is going to be connected to an external 9V power supply. The duty cycle is given in percentage and the higher the duty cycle, the higher the voltage across the motor which also increases the speed of rotation.

It is mainly compatible with the Arduino UNO and MEGA boards . The input pins IN1, IN2, IN3 and IN4 of the L293D IC are connected to four digital output pins 8, 10, 9 and 11 of the Arduino.

Another rather common driver is the L298N motor driver but unlike the L293D driver, this …

Required fields are marked with *.The L293D motor driver IC is one of the cheap and easily available devices for controlling the speed and direction of rotation of DC and stepper motors. Required fields are marked with *.The L293D Motor driver shield is one of the best way for controlling DC, Servo and Stepper motors especially if you are using Arduino UNO or MEGA in projects like robotics and CNC.

This knowledge can be got from another tutorial using this link. This motor has five wires although four wires are used to connect the coils to the L293D driver, that is, A+ (Orange), A- (Pink), B- (Yellow) and B+ (Blue). It can also be seen as a dual H Bridge driver for driving Motors. Pdf push pull four, l293d motor driver shield tutorial, arduino create getting started.

Take note that each channel of this module has the maximum current of 1.2A and doesn’t work if the voltage is more than 25v or less than 4.5v.Make sure the power jumper on the motor shield is in place.In this case make sure the jumper is removed from the motor shield. This means the motor uses only one side of the L293D motor driver, that is, ENA, IN1 IN2, OUT1 and OUT2. The VCC1 pin will be connected to Arduino 5V. L293D motor driver Module, Male burg stick connectors for supply (+12V, +5V and GND). This is achieved using an H-bridge circuit which is used for switching the polarity of a voltage applied to a load like a motor in this case. L293D can provide currents up to 600mA and L293 can provide currents up to 1A at voltages ranging from 4.5 to 36. They are connected to output pins OUT4, OUT3, OUT2 and OUT1 respectively.

When the duty cycle is 100%, the pulse is constantly HIGH and the motor receives full power and spins at its rated output speed while a duty cycle of 0% means the pulse signal is constantly LOW therefore no voltage across the motor and the motor will stop rotating.

Motor Controller driver IC’s are widely used in electronic circuits to control the motor with ease and to drive it efficiently.

I have a post with a more detailed explanation of how the PWM technique is used with Arduino which you can refer to using the link below. Latching relay drivers.

The code below is for controlling a single DC motor. The pins IN1, IN2, IN3 and IN4 are actually for controlling the switches of the H-bridge circuit of the L293D module.If IN1 is LOW and IN2 is HIGH then motor A will rotate in a particular direction and if IN1 is HIGH and IN2 is LOW then the motor rotates in the opposite direction.
