Adafruit Trinket Spider-Man Instant Kill glowing eyes
A simple recreation of the glowing eyes from Spider-Man Homecoming. Uses 2x CR2032 batteries, a 5 volt Adafruit Trinket microcontroller (similar to Arduino), red & white LEDs and a button. Simple but very effective, especially in the dark for Hallowe'en Trick-or-Treating. Off--the-shelf Spider-Man costume but with white eye grilles replaced with his older sister's black tights! Don't tell her...
