You need to use the ADC peripheral to read analog inputs. See the ADC example in SDK 12.3.0 for nRF51 devices.

Are you using the nRF51 DK (PCA10028), or some older board?

I have not changed anything in the example. i don't know if i am doing wrong anywhere. I flashed the program directly from repository. Do we need to do anything with the sample values obtained? the sample values i am getting are always in 800+. Do i need to change anything in the program?

Have you changed anything in the example? I get 512 when nothing connected, 1023 when connected to VDD and 3 when connected to GND. Could you try flashing the precompiled hex-file, found in the repository?
