The first Arduino Day event to be held in Rockville took place at the Rockville branch of the Montgomery County Public Library on April 1, 2017. Arduino Day 2017 saw 499 different events take place in 78 countries worldwide. The event in Rockville was a collaboration of the Montgomery Village Arduino Meetup group (for which I’m the organizer), MoCo Makers group (co-organizer), and the Rockville Science Center, and took place in the library’s Maker Space. The event had over a dozen displays and activities, and we estimate we drew about 50 visitors of all ages.
We have a YouTube video posted here: https://www.youtube.com/watch?v=zAmIZ5HyrRA I’m the guy in the red shirt demonstrating my Toyama Light Rail trams being controlled by my Arduino-based throttle with visitors getting a chance to take the control and drive a tram. Yeah, I look just like my avatar, don’t I? 😉
