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

If you are like us, you by no means get worn out of retro match-motivated initiatives, and the dynamic duo, [monsely], appear to love them as well. Their Temperature-Sensitive Pac-Gentleman/Ghost LED Matrix would make a good desktop display for any gaming enthusiast.

First, they did a little bit of sketching on superior ol’ paper and pencil to organize all the LEDs they would have to have and perform out the connections. With this several LEDs, coordination is rather essential or you will speedily end up with a huge mess on your hands. The good thing is, WS2812/Neopixel-type LED strips limit most of the important connections, so that was a relief. These LED strips only want a one GPIO for control, producing it easy to get this challenge going with a quite fundamental microcontroller.

Just exhibiting an animated graphic was a little bit much too basic for [monsely]. They resolved to make the Ghost temperature-sensitive, shifting to blue if it is cold outdoors and red if it’s warm. Of course, you’ll probably want to tweak the thresholds centered on where by you dwell or how your HVAC process is doing. Pac-Man stays the common yellow, which we would assume.

Of program, no excellent desktop display screen would be finish with out a good enclosure. [monsely] opted for a cardboard box, but we’re sure you could laser slice or print a thing a bit sturdier and a little bit a lot more aesthetically satisfying. But, hey, whichever operates, proper?
