As mentioned earlier, I have the source code of the demo software but just need some basic idea of how to do what I want to do?
I have recently bought a USB Relay controller which I believe is developed by Protosmart although I bought it from ebay (Here is the link if anyone is interested).
It comes with a demo software & the source code in Visual basic. What I want to achieve with this board is to play an mp3 song on my computer & then reflect the beats/rhythm on the 8 bulbs I have attached to the relay board (Like visualizations of the music). I was wodering if anyone could guide me for this?
I am a beginner with Visual basic but I hope I will be able to achieve by using the demo software & some guideline.
Thanks for your time.
If you are trying to make music visualization where 8 globes show intensity with different parts of the music spectrum then this device will not work. This device simply turns a relay on or off.
There are kits and commercial devices made over the years to do this. They are basically simple adjustable band-pass filters with some type of analogue driver for each output.

The best you can do with this device is turn 8 LEDs on and off. Relays are also not good for making things blink quickly - they are mechanical, so besides constant clicking, they have a transition time from on to off - if you want blinking to happen faster than that, this device simply wont work.
I think a better bet would be to use FusionBrain
