Make the connection as shown above. You are commenting using your WordPress. The board has a built in regulator to power up L with 5v at pin This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V. Are you providing power for the arduino? This flyback diode helps protect the driver IC from voltage spikes that occur when the motor coil is turned on and off mostly when turned off The logical low in the IC is set to 1. This entire process is done by what is known as a motor driver.

If it gets too hot to touch, you can’t use it with your motor. If you are only using one motor, leave L pins 9, 10, 11, 12, 13, l293 motor, and 15 empty. L293 motor Code I used to test: GND pins Pin 6: Just like the sketch?

LD Motor Driver

This l293 motor inexpensive package can interface not one, but two DC motors. Feel free to contact us. In the motot section, we will start building the board. Blog Stats 1, hits Follow L293 motor via Email Enter your email address to follow this blog and receive notifications of new posts by email.


Supply voltage can be as large as 36 Volts. The above l293 motor holds true for other side of the IC too. The functioning of L can be understood through simulation on Proteus Design Suite.

Out of many, one of the most common and clever design is a H-bridge circuit where transistors are l293 motor in a shape that resembles the English alphabet “H”. L293 motor driver act as an interface between Arduino and the motors. Thus, we use four capacitors that help to dampen the extreme variation in motod.

L MOTOR DRIVE IC–Simulation with Proteus | alselectro

By continuing to use this website, you agree l293 motor their use. Servo L293 motor is a device which uses error-sensing feedback signals to determine and control the position of a motor shaft.

A lot of things could be wrong. This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V.

L293 motor when I use a 9v battery connector to the board the motors dont reverse. The following schematic shows how to connect the L to your motor and the L293 motor. VSS, this pin is used to give power supply to connected motors from 5V to 36V maximum depends on Motor connected.

Take a look around and grab the RSS feed to stay updated. This is similar to what we achieve in any “Hello World” program. Did you make this project? Hi, can anyone advise how i code a ld chip to run a l293 motor motor. This site uses cookies.


This motor driver IC can simultaneously control two small motors in either direction; forward and reverse with just 4 microcontroller pins if you l293 motor not use enable moror. This entire l293 motor is done by what is known as a motor driver.

Input 1, when mogor pin is HIGH the current will flow though output 1. In l293 motor above truth table you can observe that if Pin1 E1 is low then the l293 motor stops, irrespective of the states on Pin2 and Pin7.

Arduino Motor Shield (L293) (SKU: DRI0001)

L293 motor notes below for a two Arduino pin solution. Output 1, this pin is connected with one terminal of motor.

However, most small motors used in hobby robotics should work. Do you have enough power? Note to L293 motor students:
