About Buttons Microcontrollers such as the Micro:bit all do one similar thing, accept an input (some sort of ‘message’ from the outside world), process (run some code) and output (show something to the outside world).
Servos are small motors with gearing that can add a high amount of torque (turning strength), and reliably turn to a precise angle. Servos such as the SG09 are small, cheap, run on low power
Given what we have learned about controlling the joystick and neopixel hardware in Micro:bit Joystick Module and Micro:bit Neopixels, can we construct a simple game? We need to consider the hardware, animation, random position generation
NeoPixels are Adafruit’s brand of individually addressable RGB LEDs. However the name has become common use to describe most kinds of WS2812 (and similar) LED arrays. Each LED can have it’s colour set individually using
These small joystick modules are composed of a single switch (triggered when pushing down), and two potentiometers set by moving the X and Y axis. As well as two power pins, it has three ouput
