ITP Physical Computing has a terrific tutorial on using an Arduino and an L293 to control a bi-directional motor. The L293 is simplest and inexpensive for low current motors, For high current motors, it is less expensive to build your own H-bridge from scratch. The pinout for the L293 in the 16-pin package is shown below in top view. For this tutorial we will be referring the motor driver IC as L293D only. http://vinaprosoft.com/motor-driver/l293d-motor-driver-ic.php
COIL: Its the electromagnet coil inside relay. For more info and support please mail me or leave a comment or visit my blog... Input logic 00 or 11 will stop the corresponding motor.

H-bridge is a circuit which allows the voltage to be flown in either direction. In simple you need to provide Logic 0 or 1 across the input pins for rotating the motor. Dual H-bridge Motor Driver integrated circuit (IC). L293d Arduino Scrolling through the mouser.com website for a zigbee module, i came across a product image which sh...
The maximum voltage for VSS motor supply is 36V. A motor driver IC is an integrated circuit chip which is usually used to control motors in autonomous robots. Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. http://www.me.umn.edu/courses/me2011/arduino/technotes/dcmotors/L293/L293.html It means that you can control two DC motor with a single L293D IC.
You can use the L293 to drive relays and solenoids. L293d Motor Driver Shield It must be greater than the maximum current drawn by your motor. This is met by using 2 npn and 2 pnp transistor as shown below. My Distractions 5,396 views 5:15 Arduino Tutorial #7 - How to use the L293D Dual H-Bridge - Duration: 18:33.
If we directly connect motors to the output of any of the above IC's, they might get damaged. digitalPimple 722,777 views 10:33 10. L293d Wiki Read more APR9600 sound recorder IC is no more- Use... L293d Motor Driver Board There are two Enable pins on l293d.

So, this is the Master Control pin for the left part of IC 2 INPUT 1, when this pin is HIGH the current will flow though output 1 3 OUTPUT 1, 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 Each chip contains two full H-bridges (four half H-bridges). Check This Out The motor voltage is separate from the logic voltage.
Similarly for Logic 0 (0V) on Pin 2, 0V on Pin 3 appears. L293d Stepper Motor Driver If the image is beyond the maximum dimensions, it will be resized to fit within the maximum dimensions. At this point the fluctuation in voltage is quite high and this can damage the IC.

The L293D IC receives signals from the microprocessor and transmits the relative signal to the motors. The spring holds the armature at one electrical contact and as soon as a voltage is applied across the electromagnet, it coils the armature, changes its contact and moves to another L293d Price Tech Maker 1,686 views 6:32 L293D DC Motor Driver IC (pin diagram) and Description - Duration: 3:18.

If it gets too hot to touch, you can't use it with your motor. (Note to ME2011 students: The L293 should be OK for your small motor but is not OK These are perhaps better known as "the drivers in our Adafruit Motorshield".
