If you are like us, you never ever get exhausted of retro activity-inspired projects, and the dynamic duo, [monsely], look to adore them too. Their Temperature-Delicate Pac-Person/Ghost LED Matrix would make a fantastic desktop show for any gaming fanatic.
Very first, they did a little bit of sketching on very good ol’ paper and pencil to organize all the LEDs they would will need and work out the connections. With this many LEDs, coordination is rather crucial or you are going to quickly end up with a significant mess on your palms. The good thing is, WS2812/Neopixel-design and style LED strips lessen most of the required connections, so that was a aid. These LED strips only will need a solitary GPIO for regulate, producing it straightforward to get this challenge likely with a rather basic microcontroller.
Just exhibiting an animated graphic was a bit way too very simple for [monsely]. They made a decision to make the Ghost temperature-delicate, shifting to blue if it’s chilly exterior and crimson if it’s warm. Of program, you are going to almost certainly want to tweak the thresholds dependent on wherever you live or how your HVAC procedure is carrying out. Pac-Guy stays the vintage yellow, which we would anticipate.
Of training course, no superior desktop exhibit would be complete without the need of a good enclosure. [monsely] opted for a cardboard box, but we’re sure you could laser lower or print a little something a little bit sturdier and a bit a lot more aesthetically satisfying. But, hey, no matter what will work, right?
