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


If you’re like us, you never get tired of retro activity-encouraged assignments, and the dynamic duo, [monsely], appear to be to love them too. Their Temperature-Sensitive Pac-Man/Ghost LED Matrix would make a good desktop screen for any gaming enthusiast.

1st, they did a bit of sketching on very good ol’ paper and pencil to organize all the LEDs they would need and get the job done out the connections. With this many LEDs, coordination is fairly important or you are going to quickly stop up with a significant mess on your arms. Thankfully, WS2812/Neopixel-type LED strips minimize most of the required connections, so that was a relief. These LED strips only have to have a solitary GPIO for manage, generating it simple to get this job heading with a very essential microcontroller.

Just exhibiting an animated graphic was a little bit far too very simple for [monsely]. They decided to make the Ghost temperature-sensitive, transforming to blue if it is cold exterior and crimson if it’s warm. Of system, you’ll in all probability want to tweak the thresholds based mostly on where by you are living or how your HVAC method is doing. Pac-Man stays the basic yellow, which we would be expecting.

Of study course, no excellent desktop screen would be complete with out a correct enclosure. [monsely] opted for a cardboard box, but we’re certain you could laser minimize or print a thing a bit sturdier and a bit much more aesthetically pleasing. But, hey, whatever operates, proper?
