"Physical" Like Button

Inspired by Facebook "Reactions". You press the button, and the number count gets displayed on the LED screen.

Looks like a novelty product, but this can be used for all sorts of useful stuff like keeping track of attendees at an event, keep track of a score for a game or anything else that needs a tally counter.

Customize it, Make it!

The really cool thing about this is that you can build your own with a just few components and a 3D printed case.

To make your own, you'll need an Adafruit Trinket, a 7-segment LED display and an Arcade button.
