6 Arduino projects to play with on Arduino Day

A lot has changed since the first Arduino board arrived a decade ago. Today, the Arduino family has grown to include more than two dozen low-cost, open hardware boards and an active community of more than 250,000 tinkerers. With Arduino Day 2015 just around the corner, I’ve rounded up some of my favorite Arduino projects, tools, and articles to get you excited and inspired. So whether you’re celebrating at one of the many community events or digging in to a project on your own, happy tinkering!
