lf356 circuit
dear friends
this circuit is used to measure light intensity using the following basic analog circuit .... now i want to use microcontroller (89c51) and adc -AD7922 (12 bit)
so that i can include some more functions and also 16 x 2 lcd . in the present circuit two pots are used one for zero setting and other for calibration in 741 section . can these two be removed using programming technique.... the output voltage of lf356 varies from 0- 60 mV ....
how can i change the circuit to make it fully microcontroller based to that i can do the settings using keypad control.....
can anybody help me out with this please
thank you
