Five-Direction Joystick
A five-way navigation switch on one analog pin: four tilts and a press, each joining SIGNAL to its own point of a chain of 10 kΩ resistors, so each push is its own voltage. Read it with analogRead, not digitalRead. VCC is your board's logic voltage.

Mechanical Key and LED
A keyboard switch with a WS2812 RGB LED under its clear keycap, as two separate circuits: the key reads HIGH when pressed through its own 10 kΩ pull-down, and the LED shows whatever colour your sketch sends it. VCC is your board's logic voltage.
