Hello,
Is there a way to convert arduino nano digital pins to take analog value. I need it for my project.

 

hi AD,
The Arduino Nano already has Analog pins.?

See the section 1/2 way down the page on nano Analog pins.

If you actually want to use a digital pin for analog input, an LM339 comparator will switch from 0 to 1 at whatever voltage you like.
If you need more than the 8 analog pins supplied, you could use an analog data selector like the HCF4529b.

There are others.
