Temperature-Sensitive Pac-Man/Ghost LED Matrix | Hackaday

If you’re like us, you hardly ever get exhausted of retro video game-encouraged tasks, and the dynamic duo, [monsely], seem to be to appreciate them also. Their Temperature-Sensitive Pac-Guy/Ghost LED Matrix would make a excellent desktop display screen for any gaming fanatic.

First, they did a bit of sketching on good ol’ paper and pencil to arrange all the LEDs they would want and do the job out the connections. With this quite a few LEDs, coordination is very significant or you’ll promptly finish up with a large mess on your hands. Fortunately, WS2812/Neopixel-design and style LED strips limit most of the needed connections, so that was a reduction. These LED strips only need to have a single GPIO for control, producing it effortless to get this challenge likely with a pretty basic microcontroller.

Just displaying an animated graphic was a bit much too uncomplicated for [monsely]. They made a decision to make the Ghost temperature-delicate, switching to blue if it’s chilly outdoors and purple if it is warm. Of training course, you’ll likely want to tweak the thresholds based on exactly where you stay or how your HVAC method is executing. Pac-Guy stays the typical yellow, which we would assume.

Of system, no very good desktop display screen would be comprehensive devoid of a suitable enclosure. [monsely] opted for a cardboard box, but we’re certain you could laser cut or print a thing a little bit sturdier and a little bit far more aesthetically pleasing. But, hey, what ever functions, correct?
