C# software ( 4.0 .net framework)
PIC18F4550 Firmware - for 6 LED's.
TUTORIAL FOR BEGINNERS
It’s a low cost USB interface Board that provides cool interface to your computer and it can be used to control various devices like DC Motor, Stepper motor ,Servo ,relay switch etc. with your laptop or any computer with a USB port and dot net framework installed. A small C# program communicates with the hardware to issue commands to set the pins of the Microcontroller. IN spite of LEDS u can use it as control signals for your project.
USB controlling is cooler than that of parallel port. Rather laptops now days don't come with parallel port, so a USB port is a bit easy replacement. The Video will show you my USB Interface Board, see its working, I will post links for making your own Micro-controller board .
As arduino Boards are very costly and if are beginner with microcontroller then you really don’t wanna invest so much on a arduino board for the 1st time on microcontroller, rather if you make one mistake then you microcontroller is fumed (like exceeding Vmax of microcontroller).
The Video below will show you my USB DEMO INTERFACE DEVELOPMENT BOARD, see its working and in the end I will post links for making your own Microcontroller board.
I WILL PUT TUTORIAL TO MAKE THIS BOARD AT THE END PART.
BEGINNERS: Microcontroller projects are not like ordinary circuits (follow schematic and you are done) In case of Microcontroller board there are lots of steps. Microcontrollers are like Artificial Mind of a ROBOT.
USB Demo Interface Development Board (PIC18F4550) : Tutorial for making this Board is Lengthy, so I will post the links for making this board.
This a USB Demo Interface Device , that allows me to control 6 led's, i have used a pic18f4550 microcontroller , i have found the schematics and diagrams on microchip.com to make it. I have modified it control 6 led's , it is provides a cool interface to my computer using USB port and leds are controlled with clicks or pressing numpad buttons on my laptop.
It can be used to control various devices, like, Stepper Motor, servos, DC motor, Relay switches etc. etc. etc.
Download the firmware code ( for 6 - 8 leds) and C# application..
I Found this Nice Tutorial on a website while i was searching for some tutorial for making this board, i made a robotic arm based on this USB Interface Board, At beginning i thought of using Parallel Port but laptop don’t come with laptop , so using a USB port is a cool replacement of parallel or serial port with more better performance .This tutorial is actually not mine but i found it on a website and so sharing with all :)
UNFORTUNATELY FOR BEGINNERS THE DETAILED INFORMATION AND TUTORIAL STEP BY STEP CONSTRUCTION CAN BE VERY LENGTHY.
SO I AM GOING TO POST LINKS OF A DETAILED TUTORIAL

NOTE: IF in case the links above are not working then please come back later after some hours , the website goes goes down sometimes (sorry about it) , though i have attached the C# APPLICATION and 6 -led controlling at the end for Advance users here. But If you are really new at microcontroller stufsfs then please wait for sometime in case if the links are are not working. The Links explains everything in Details.
