What is the sensor ?
Is it on/off or does it give a variable level ?

"Can anyone help me me out how can i do this"
Start by dimming one led.
Do that by switching it on and off very fast.
The technique is called Pulse Width Modulation (PWM).

Do you know anything about using interrupts on the 8952 ?
