hi,
R u going to use 8 bit ADC or 10 bit ADC. 8 bit ADC value ranges from 0-255 so it will require 3 digit 7 seg display and for 10 bit ADC 4 digit seven seg display. For changing ADC value u can attach one knob to ADC IC input so that when u will revolve knob input will change and thus ADC value accordingly.

M going to use 8 bit ADC only.. But how value will convert for 7-Segment, Can You Please explain me coding for this...
Thank You......

Integer value should ne converted to character. An array should be used for 7 Segment codes either for CC or CA.

hi,

do u know how to display the data on 7 segment display? if yes , then its easy. take an array for numbers from 0-9. when u vl have 8 bit ADC output which will b in the range 0-255, separate the numbers , link it with numbers in the array and display it on selected fnd as simple as that. Data for the numbers from 0-9 in array will change according to routing.
