More Spoooky CircuitPython Circuits

Here’s two more “Spoooky CircuitPython Circuits” using the QT Py board and purposefully small programs, part of my QT Py Tricks series. Go there for the source code. The first circuit is a pair of OLED displays arranged like eyes. Behind a mask it looks really good!

The second circuit is the old trick of using capacitive touch sensors in an analog proximity mode. The result can be pretty twitchy and highly dependent on environment and power supply, but it looks good on camera! :-) And in a more defined use (like on a PCB) can give repeatable results, like the “analog” A input on my TrinketTrigger Eurorack module.
