Badges made to hand out as a teaching exercise for the IEEE UIUC exhibit at Engineering Open House 2016. When you cover up the light sensor, the badges play along and flash to “Hail to the Orange”. You can see a video of the build in action here. This exhibit won second place in the “Just for Fun” category!
