https://devzone.nordicsemi.com/f/nordic-q-a/96136/blinking-an-external-led-on-nrf9160dkDear Nordic Team, I am currently using nrf9160dk to blink an external LED that is connected to Pin0.14. However, I am unable to blink the LED with the code below. May I know how to solve this issue?

Are you able to build the code? I tried building but I ran into some build errors. Which nRF Connect SDK are you building for?&nbsp;</p> <p></p> <p>In the documentation for the standard <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.2.0/zephyr/samples/basic/blinky/README.html">blinky</a> sample there is a section about <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.2.0/zephyr/samples/basic/blinky/README.html#adding-board-support">adding board support</a> that shows how to change the pin. If you add this to an overlay, and change from <code><span>gpios</span><span> </span><span>=</span><span> </span><span>&lt;&amp;</span><span>gpio0</span><span> </span><span>13</span><span> </span><span>GPIO_ACTIVE_LOW</span><span>&gt;</span></code><span></span></p> <p>to <code><span>gpios</span><span> </span><span>=</span><span> </span><span>&lt;&amp;</span><span>gpio<span style="background-color:rgba(255, 255, 153, 1);">0</span></span><span style="background-color:rgba(255, 255, 153, 1);"><span> </span><span>14</span></span><span> </span><span>GPIO_ACTIVE_LOW</span><span>&gt;</span></code>, then you should hopefully see your LED on P0.14 flashing.</p> <p>Best regards,</p> <p>Håkon</p><div style="clear:both;"></div>
