i'm trying to interface my arduino mega with a photodiode (BPW41), but i was wondering how to connect it to the arduino ...
i saw on a wiki that this photodiode needs to be be reverse biased
someone knows how to get it to work ? (maybe links or a scheme would be very apriciated)
and, when i have to interact with it, what could i read ? HIGH level when he got ir beam and LOW when ir goes out ? how could i trace the data value to make something like a sensitivity regulation ?
thank you all
