You-Do-Electronics Center (YDI) — a local store that’s also a source of STEM awareness and inspiration for the community — will host two events:  Arduino Day (March 21) and Robo Day (April 4, during National Robotics Week). Both events will be 11AM-4PM, filled with exhibits, activities, raffles, and special offers related to STEM. (See photos of last year’s Robo Day.) If you have an Arduino/Robotics project to showcase, or if you represent a STEM-related organization and would like to be an exhibitor at one or both events, email events@youdoitelectronics.com to reserve a table. YDI is at 40 Franklin Street in Needham, between Rte. 128, the Charles River, and Highland Avenue.
