L 293d Motor Driver


The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15. I have a question that I think you may know the answer to. Are there types of crystals, if yes, which type should I use??? Durfee The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. have a peek here

I have the same exact one.

How To Use L293d

Yes, I am a n00b! ;) Thank you! All in All When there is lite it turns on the motor for 5 sec on one side (lets say left) when there is no light it turns the motor for These are perhaps better known as "the drivers in our Adafruit Motorshield". Thanks!

  • If the image is beyond the maximum dimensions, it will be resized to fit within the maximum dimensions.
  • If anyone of the either pin1 or pin9 goes low then the motor in the corresponding section will suspend working.
  • The maximum voltage ranges from 5v and upto 36v.
  • So be careful with this or you can burn your motors!Correct, If you want to connect an external power source you have first remove connection from 5V.
  • TIP: you can simply connect the pin16 VCC (5v) to pin 1 and pin 9 to make them high.
  • since i only need them to run in one direction, i can use all positive pins available while sending all the negatives from the motors together..

Runs at 5V logic. Password * Confirm password * Provide a password for the new account in both fields. They do handle a peak of 1.2A but that's just for a short amount of time. L293d Arduino Good for motor voltages from 4.5V up to 36V!

Lets consider a Motor connected on left side output pins (pin 3,6).

In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction.

Just connect the relay coil or solenoid between one of the driver outputs (pins 3, 6, 11, or 14) and ground and turn it on or off with the control pin

What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project When I check the current flowing through a single motor with a multimeter, it peaks at about 80mA for the given script and upwards of 160mA with continuous use. Remember that L293 IC can drive only 0.5A per channel (for each motor).Liamthe1st (author)Reply2015-08-17I am a in UK a full Member Pro etcLiamthe1st (author)Reply2015-08-17for some reason down load PDF is not Thank you!

High voltage on low voltage input?hiponiaE (author)Reply2016-03-12Hello about the L293D motor IC what are the other replacement for it.? You can Buy L293D IC in any electronic shop very easily and it costs around 70 Rupees (INR) or around 1 $ Dollar (approx Cost) or even lesser cost. And that's it, you've programmed your Arduino board!You can keep playing with that by clicking the "Edit" button and start making your own modifications to the code.

Left input pins will regulate the rotation of motor connected across left side and right input for motor on the right hand side. Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state. Pin Diagram:Pin Description:  Pin No Function Name1Enable pin for Motor 1; active highEnable 1,22Input
