Dear Sir,
I am looking for a circuit, with two( or three) 7 segment LED displays, connected to a wirewound potentiometer of 1M or 10 M, display shows "00" at lowest value and "99" at highest value. Kindly please help me in this regard.

THANKS
REGARDS,
Prabhu
 
Connect the pot end to 0.99V. Connect the wiper to an LED digital voltmeter. (You can block the decimal point so it will read 99 instead of .99 at full scale.)

Hi,
Crutschow aka Carl has given a simple solution.:)

Connect the pot end to 0.99V. Connect the wiper to an LED digital voltmeter. (You can block the decimal point so it will read 99 instead of .99 at full scale.)

To do it with discrete logic would be a task, are you able to use a PIC.?
