ou are running a small "geek shop" and want to impress the first/last customer of the day? You want to leave your desk for a short break and think telling that to your colleagues - and to Alexa - should be enough effort (why should you leave a note)? Or just to show the world how cool you are? Or just for fun? ... ;)
This is just a demo, a prototype, a short sketch or quick recipe, how to control an e-paper display connected to an Arduino MKR1000 using Amazon's Alexa Skills Kit.
