NEW GUIDE: Circuit Playground Beep Beep
In the original Star Trek series, there are a couple of episodes that feature a severely disabled Captain Pike (former captain of the Enterprise) who is immobilized and can not speak. He can only communicate via a little light on the front of his wheel chair. It blinks (and beeps) once for “yes”, and twice for “no”.
We can create a similar yes/no functionality using our Circuit Playground. We can use the buttons to select “yes” or “no”. The speaker can provide the characteristic monotonic “beep”, and the NeoPixels can act like the light. In fact, the resulting program is pretty simple. However, it serves as a good way to introduce a fairly advanced coding topic – refactoring.
We will start with a fully functional program and then incrementally go through it and show how it can be “improved” by applying various refactoring techniques.
