CircuitPython 101: State Machines, Two Ways If I g

This new guide in the Adafruit Learning System goes over the development of State Machines for tracking the state of an electronic project.

What’s a state? Let’s use the example of the states of matter: solid. liquid, and gas (we’ll ignore plasma to keep this simple). There are well defined transitions to move between these states:

  • melting transitions from solid to liquid,
  • freezing transitions from liquid to solid,
  • evaporating transitions from liquid to gas,
  • condensing transitions from gas to liquid, and
  • sublimating transitions from solid to gas.

Each of these have conditions in terms of material, temperature, and pressure that control whether or not the transition can happen. A simplified example of this is that when its temperature is less than 0C (32F), water will freeze transitioning it from a liquid state to a solid state.

The guide describes two methods using the recently released New Year’s Eve Ball Drop tutorial as a demonstration. Algorithms are coded in CircuitPython.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
