through 8255 peripheral. There are 8 select channels‚ IND to IN7 through which we can provide an analog input to ADC which we have obtained from an analog device. This output can be electrical signals of transducers measuring temperature‚ depth‚ pressure‚ etc. in the form of an output voltage. We see that there are 8 input channels for ADC and we can use 8 different inputs at a time. Now the output of this ADC is fed into the input of 8051 micro controller. Through a 8255 peripheral.
