Halloween

Minerva, AdaBot, and Blinka wear Halloween masks and dance around a bonfire at night

It’s our favorite time of year - a liminal time when the boundary between the physical and spiritual thins - and when banshees, bats, and broomsticks blend with bots, batteries, and breakout boards.

It can sometimes be more trick than treat when trying to pick the right flourish to tie together your costume design or finish your fright-tastic front-lawn setup. This guide, which highlights some of our spooky season favorites, is here to help. 

For those of you who don't know exactly what your mad scientist is cooking up, we also suggest Adafruit Gift Certificates.
