Hey all ! How are you been doing so far ?
In this article, I will explain briefly on a simple motor driver IC - L293D.
This is a Dual H-bridge motor driver. In other words, this IC are able to control 2 DC motor at the same time.
This IC are able to control to :
- Control the speed of the rotation of the DC Motor
- Control the direction of rotation of the DC Motor. For example either rotate clockwise/anticlockwise.
The L293D IC have 2 VCC pins as you can see - VCC1 and VCC2.
- VCC1 is for the supply voltage to power up the IC( Never exceed 5V! )
- VCC2 is the supply voltage for your motor. ( Up to 36V ! ). However, please have a look at the specifications of the motor you used. Some motor can't withstand such a high voltage.
Example connection :
I have made a simple application using this motor driver IC - VK 2WD Electric Car Controlled through Android Application !
Have a look here :
I hope that this simple article will help you understand about how a L293D motor driver IC works and how it can be applied to make something fun !
