In this tutorial we interface a tactile switch to the micrcontroller and display it on a LED. To download code, schematic visit: exploreembedded... If you've any doubts just comment on the page, we are here to help you build!
A well made and easy to follow video. You're doing a great job. I would request if you would make more videos on the in-built libraries and the atmel studio 6 environment
Thanks for the video. Gat a question though. Around 4:10, was the use of the external pullup resistor necessary since the GPIO pins have internal pullups already?
