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

Clara D. Flaherty


If you’re like us, you by no means get worn out of retro recreation-inspired projects, and the dynamic duo, [monsely], feel to like them too. Their Temperature-Delicate Pac-Gentleman/Ghost LED Matrix would make a great desktop exhibit for any gaming fanatic.

Very first, they did a little bit of sketching on fantastic ol’ paper and pencil to organize all the LEDs they would need to have and do the job out the connections. With this quite a few LEDs, coordination is rather vital or you will quickly stop up with a significant mess on your palms. Luckily for us, WS2812/Neopixel-design LED strips decrease most of the important connections, so that was a reduction. These LED strips only will need a single GPIO for regulate, earning it simple to get this project heading with a pretty simple microcontroller.

Just exhibiting an animated graphic was a little bit way too uncomplicated for [monsely]. They made a decision to make the Ghost temperature-delicate, shifting to blue if it is cold exterior and purple if it’s heat. Of program, you’ll most likely want to tweak the thresholds primarily based on exactly where you dwell or how your HVAC system is undertaking. Pac-Male stays the classic yellow, which we would expect.

Of program, no excellent desktop display would be total without having a correct enclosure. [monsely] opted for a cardboard box, but we’re sure you could laser slice or print a thing a little bit sturdier and a little bit a lot more aesthetically satisfying. But, hey, whatever operates, right?
