Deep Dive
Before moving forward, let's take a moment to more closely examine the code for this project and how it works.
This MakeCode example provides instructions for a 60 second countdown and provides visual & audible warnings at 30 seconds, 15 seconds, and 5 seconds. The code also allows the user to pause and restart the countdown whenever they need to. When the countdown hits 0 it beeps and flashes continually until it's tossed to the next speaker, at which point the countdown automatically restarts.
Let's take a look at how each of these functions are coded in MakeCode.

Startup

Here you can set the length of the timer, adjust the sensitivity to being shaken, change the volume of the beeps, etc.
On startup, the board will show the rainbow animation for 1 second before illuminating two NeoPixel LEDs at their starting point, indicating it is ready. |

Tick Tock
In this pink input block, there are some instructions telling the timer when and how to operate.
As you can see in the |
This while statement also allows the user to pause the timer if necessary and restart it again right where it left off.
Flipping the slide switch to the left will pause the countdown.
Flipping the switch to the Right again primes the countdown, and pressing the A button starts it counting down again.
