hiiii guys,
How to interface photodiode with microcontroller??In my project input is not a single photodiode,there is 8 photodiode.I think I have to use analog mux for converting 8 input to 1 and send that output to microcontroller.Isn't it???? thanks in advance.

You could use the multiplexer , and use the micro to average them.
Or you could feed the signal levels into a summing amplifier and then divide the output back down again to get the average without any computing.
