Hi to all, Im new on the PICBASIC world...
I need to programming a PIC (if it is possible a 16F84) with a PICBASIC code that:

-Read by a photoreceiver the flashing of a green ligth (visible) led
-show on a LCD display the time between a blink (flash) and the next. The led flashing never stop but frequency could change.

tipical frequency is from 2Hz (2 blink/sec) to 0.05 Hz (20 sec between a flash and another)

I would like if you could provide me a circuit to do it, also.

Thanks a lot.

Dario
