Is there any way i can use the analog input pins of an atmega328p microcontroller to give output? All my other digital I/O pins have been used up.

Analog (A0, A1, A2, ...) pins can be used as digital pins, so you could use them with "digitalWrite()". 
pinMode(A0, OUTPUT); digitalWrite(A0, HIGH); digitalWrite(A0, LOW);
