Introduction

"Where's Bobby?" A question that comes up when at work. While I'm usually at my desk, there are times that I need to walk away for lunch, take a 15-minute break, head into a meeting, or check inventory. To help notify others of where I may be, I made the Qwiic-enabled digital desk sign using the SAMD51's USB host and a USB keyboard to type short custom messages while I am away!
