i have a problem, im making a digital temperature proyect, i used a LM35 that equals 100mv to 10C*, and a analog to digital decoder, that makes it binary, and heres my problem

When i try to display any temperature that surpasses 9, the display gives me the hexadecimal letters, how can i hook up 2 7 segment displays and and make it display 1 on a display and 0 on the other

Here i have made a digital thermometer using LM 35. Check out the circuit for digital voltmeter on this site and also the discussion on it.
LM35 gives the proportionate voltage which will be measured be the voltmeter. Use the voltmeter for 2V full scale reading. I will post the circuit diagram tomorrow.
