This one-button device can do many things
December 10th, 2018—
Bigger isn’t always better, as illustrated nicely by this device from YouTuber “Volos Projects.” It’s not only physically quite small, squeezing an Arduino into a 40x25x25mm aluminum enclosure, but uses an interface consisting of a single button (plus a power switch). Data output is handled via a similarly tiny 64×48 pixel OLED display.
Regardless of its minuscule size and binary input method, it can still be utilized for a variety of functions, including as a stopwatch or counter, or even to play Flappy Bird.
Demonstration and build footage can be seen in the clip below, while a parts list, code, and electrical diagram can be found in the video’s description.
