WOW!!! Did I just made it... 
YES I AM...
I thought that I have to etch the sensor circuit which will be the long process, but had a quick thought and created with prefboard...
The process was kind of quick and I decided to put all together and did a quick test run...and...that was really amazing with everything works GREAT...
It seems the hardware process was well went and works great without a fail, but, I found that self ambient reflection causing some trouble to switching LEDs, and I am sure it will be the code that need some tweaks on ADC value range of each LED category...I will work that out and post my final woking video, as I said before that I am not going to test this in my car...stay tuned...
