Slim Joystick
A thumb stick and six buttons on one long TinkerBlock board, on six pins. X and Y are two potentiometers, read on analog pins; KEY is the click under the stick, LOW at rest and HIGH when pushed; and all six buttons share BTNS, one analog pin, through a ladder of 10 kΩ resistors that gives each its own voltage. One button reads at a time.
Latching Button
A push-on, push-off switch with its pull-down and a red indicator LED already fitted: one press turns SIGNAL HIGH and it stays HIGH, through a reset or a power cut, until the next press.
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.
Push Button
A 12 mm momentary push button with its 10 kΩ pull-down and a red press light already fitted: SIGNAL reads HIGH while the button is down. The first input in the kit, and the module that teaches debouncing.
