Here's a simple, fun project for sunny days, or dark rooms. We'll take a Circuit Playground Express and a micro servo and make a pair of automatic sunglasses/flashlight.
- A pair of glasses, an old/cheap pair preferrably.
- Flip up sunglasses, or a cheap pair with the arms removed.
- Hot glue and glue gun
- Depending on how you want to wire the servo, you'll need soldering equipment or alligator clip jumper wires.
