if amplitude of input signal is 1.5V or more - use schmitt-trigger element like 74HC/HCT14 to convert to logic level.
if level is less, add simple transistor-amplifier:

Precision RTC using ATMega8 and DS3231. Indication: 4-digit 7-segment (up to 42V 500mA on each segment), remote control (Sony RM887), temperature sensor (external DS18B20 or internal from DS3231), brightness correction with external photoresistor.
Additional work mode - show static 4-digit...
