USB DC Motor Controller using PIC18F4550
USB DC Motor Driver using PIC18F4550
Schematic pic18f4550 Interface L293D
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 working of the this project is very simple
USB + C# [HID] > pic18f4550 > l293D > DC motor
WORKING OF THE L293D MOTOR CONTROLLER
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 don't know about costs in other country :) :).
You have to make my USB Interface board first to make this project done, once you are done connect the l293d with power and connect it with pic18f4550 as I have mentioned in the video "INTRODUCTION to L293D" or follow the schematic.You can easily make this entire circuit on breadboard or a PCB.
Thats all you need, thanks for watching
