I was thinking of using a PWM signal for the LED. 12F683 could be handy here.
Start the HPWM of x KHz, and use the internal timer to count in background. With a decent prescaler, it should reject most part of the ambient light.
Just an idea... in theory it works.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Thanks for the details Sougata. I am definitely taking all info into consideration.
And For 12F683, I will check the price and see if it is any advantage over using 12F675.
I am currently working on this thing.

More codespace
1 Hardware PWM
internal OSC up to 8 MHZ
If i refer to digikey, the price difference for a single 8pin DIP is in the worst case 0.36$ mmm, i know, sometime it's enough.

Sometimes I think that I can even sell parts to Digikey.
If you know what I mean.
