USB:- DC Motor Controller using PIC18f4550 (keyboard)
Hello friends,
This a small project on controlling D.C motor with USB pic18f4550 interface board with L293D motor controller.
A small application [C#] is controlling my pic18f4550 USB interface board with my computer, enabling me to control my board with keyboard. The output of the microcontroller is given to the input of a l293d motor controller , hence enabling me to control my DC motor in ( forward / reverse ) that is Clockwise and Counter Clockwise | anti-clock (cw/ccw) direction.
If you really interested in robotics and controlling stuffs then one of the most basic thing is to control your own applications like DC Motors , Stepper Motors , Servo (with pwm) etc etc. So lets do it with kind of absolute beginner level with DC motors.
IF you are really beginner then i suggest watch all the three videos.
The USB Device project i have already done before here http://www.instructables.com/id/USB-Project-USB-Interface-Board-Using-PIC18F455/ you can download the C# application [pic18f4550 board tutorial] from the link.This demo board enables to use Keyboard. this l293d motor controller is just a application of the USB Interface board.

The working of the this project is very simple
USB + C# [HID] > pic18f4550 > l293D > DC motor
WORKING OF THE L293D MOTOR CONTROLLER
ABOUT L293D
You can find the pin diagram of l293d motor controller with a short google, the chip is kind of self explanatory when you see it. With one single chip you can control two D.C motors to rotate in forward/ reverse direction on your command.
This chip understands only logic 0 and logic 1 signals as input control signal , we are going to generate the logic 0 and 1 with the help of a pic18f4550 microcontroller , the logic 0 and 1 will be fed to the input of the l293d and motor will be connected to the out pins of l293d.
Watch the video below
A bit more detailed video for this motor controller, you can use it the way you want it, like robotic arms.
A Single L293D motor controller chip enables you to control two motors, [two motors per chip] , in India the price of l293d costs around 80 rs/- , i dont know about costs in other country :) :).
