Digi-Key Continuing Education Center, hosted on Design News, will get you up to working speed quickly in a host of technologies you've been meaning to study, but haven't had the time, via a series of 45-minute online lessons – all without leaving the comfort of your lab or office. Our faculty of expert tutors has divided the interdisciplinary world of design engineering into five dimensions: microcontrollers (basic and advanced), sensors, wireless, power, and lighting.

All of these topics will be tackled in a dedicated week of interactive tutorials where you can ask questions of the tutor, discuss knotty issues with your fellow students, and download a wealth of additional learning materials. (Don't worry if you can't attend a particular course live – seminars are also archived, and our online educational discussions take place 24 hours a day.)
