Dear friends,
Here i am uploading a sample video, this is based on effects of PWM (pulse width modulating) signal on a LED devices, and here we have showed that what changes comes on the LED devices when we change the width or duty cycle of a PWM signal.
In this project we have used two push switches to control our system, one switch for increment in duty cycle and second one is for decrements in duty cycle of PWM signal.
We have used a point LED to shows the effects. So this is clear by this video that when we increases the duty cycle of PWM signal, intensity of LED increases, and when we decreases the duty cycle then LED intensity also decreases.
This project is developed using vhdl code, and xilinx spartan series devices are used to configure our system.
I hope you like this video. Thank you for watching.

I would love to read your suggestions and comments here,
