Building a task manager using periodic scheduling

Setting up a timer to behave as a periodic task is exactly the same as setting up a timer in MicroPython for any other purpose. We can create an application very similar to our round-robin scheduler using timers by initializing a timer for each task in the application. The first timer will control the blue LED, while the second will control the green LED. Each timer will use a callback function to the task code that will be executed when the timer expires.

We can use the exact same format for our code that we used previously. We will initialize the blue LED as on, and the green LED as off. This allows us to let the timers free-run and generate the railroad pattern that we saw earlier. It's ...
