there are 8 inputs for analog voltage in ADC0808 to convert it into Binary.
and those pin can be selected by the three pin, they are 25,24,23. but in my case only input IN0 or pin no 23 is only active, whatever i do with the ADD A,B,C pin.
000 only in this case the voltage input must be entered to ADC. but 001or010 it is also happening the same. i'm using Two analog input IN0and IN1 and rest of them i simply give them ground.
i can get the result with IN1. what should I do. I also add the Pin details of ADC0808.
thanks in advance.View attachment 66925
