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

If you are like us, you under no circumstances get drained of retro game-influenced tasks, and the dynamic duo, [monsely], seem to really like them also. Their Temperature-Sensitive Pac-Person/Ghost LED Matrix would make a terrific desktop exhibit for any gaming fanatic.

1st, they did a little bit of sketching on good ol’ paper and pencil to organize all the LEDs they would have to have and operate out the connections. With this a lot of LEDs, coordination is fairly critical or you’ll immediately conclusion up with a massive mess on your palms. Luckily for us, WS2812/Neopixel-design and style LED strips lessen most of the required connections, so that was a aid. These LED strips only have to have a one GPIO for handle, generating it easy to get this challenge likely with a very standard microcontroller.

Just exhibiting an animated graphic was a little bit also very simple for [monsely]. They made the decision to make the Ghost temperature-delicate, shifting to blue if it’s cold exterior and purple if it’s heat. Of study course, you will most likely want to tweak the thresholds based mostly on the place you dwell or how your HVAC process is carrying out. Pac-Gentleman stays the common yellow, which we would anticipate.

Of training course, no fantastic desktop display screen would be comprehensive without a appropriate enclosure. [monsely] opted for a cardboard box, but we’re confident you could laser cut or print a little something a little bit sturdier and a little bit extra aesthetically pleasing. But, hey, whatsoever works, appropriate?
