Hii Amunyela, where did you find this header file nrf_gpio.h file?can you share the link or document it will be helpful?
please do reply fast.

Hi Joakim, where did you get these instruction from? If there a manual/documentation for these? A link to that will be great man. Thank you very much!

Hi Nikhil!

As endnode said in his answer, the blinky example is a good place to start.

In my opinion the easiest way to control the LED is to use the nrf_gpio interface directly.

Configuring a pin as output: nrf_gpio_cfg_pin_output(pin_number);
Turn on/off the led: nrf_gpio_pin_set(pin_number); / nrf_gpio_pin_clear(pin_number);

Toggle the LED: nrf_gpio_pin_toggle(pin_number);

Which pin that is connected to the different LEDs, you can find in the product specification, or on the backside of your nRF51 DK.

You are probably looking for LED blinky example in SDK v12.3.0 (the newest which supports nRF51 chips).

(As this is pretty basic example mentioned in every beginners' tutorial one would wonder how long have you tried to solve your question yourself before posting to the forum;)
