L293d motor driver circuit diagram arduino.
The schematic diagram below shows a simplified version of the internal circuitry that controls one motor.
Driver ic l293d is available as module and arduino shield.
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.
It can control both speed and spinning direction of any unipolar stepper motor like 28byj 48 or bipolar stepper motor like nema 17.
Arduino dc motor speed and direction control with l293d motor driver.
The most commonly used motor driver ic s are from the l293 series such as l293d l293ne etc.
How the l293d works.
In the case of using servo motor pins 9 10 2 are in use.
One of the easiest and inexpensive way to control stepper motors is to interface l293d motor driver ic with arduino.
Each channel on the ic can deliver up to 600ma to the dc motor.
With circuit diagram and arduino source code.
The l293d motor driver s output channels for the motor a and b are brought out to pins out1 out2 and out3 out4 respectively.
Connect the pin 3 of the l293d to one end of the motor.
Connect the pin 2 of l293d to the pin 6 of the arduino.
Sometimes it can be extremely hot.

How to use arduino l293d motor driver shield.
Motor driver act as an interface between arduino and the motors.
A motor driver is an integrated circuit chip which is usually used to control motors in autonomous robots.
These ics are designed to control 2 dc motors simultaneously.
The l293d is a dual channel h bridge ic capable of controlling two dc motors.
L293d motor driver modules usually come with an inbuilt lm317 voltage regulator circuit or similar voltage regulating circuit along with connectors.
The l293d is designed to provide bidirectional drive currents of up to 600 ma per channel at voltages from 4 5 v to 36 v at pin 8.
You can use it to control small dc motors toy motors.
L293d shield is a driver board based on l293 ic which can drive 4 dc motors and 2 stepper or servo motors at the same time.
The speed is controlled using a potentiometer connected to pin a0 and the direction of rotation can be changed with a pushbutton connected to pin 8.
Connect the pin 1 of the l293d ic the pin 7 of arduino.
While using this shield 6 analog pins which can be used as digital pins too pin 2 and pin 13 of arduino are free.
The l293d can control up to two dc motors rated from 4 5v to 36v.
You can connect two dc motors having voltages between 4 5 to 36v to these terminals.
First of all we will connect the l293d motor driver ic with the arduino.
