One of the main differences of coding for an MCU is that they offer very few resources. It is generally not possible to use large Python libraries such Numpy or Scipy.
The current assignment requires you to implement a filter while working around these limits.
The game we will adapt in this assignment simulates a lunar landing module (LLM) landing on the moon. You are the pilot and need to control how much fuel you burn in the retro rockets so that your descent speed slows to zero just as your altitude above the moon's surface reaches zero. If you impact the moon more than 5 m below the surface, or your speed on impact is greater than 5 m/s then you have considered to have crashed. Otherwise it is considered to be a 'good' landing. If you run out of fuel, LLM will accelerate towards moon by gravity.
For more on the history of this simple but influential game, see, for instance: https://www.technologizer.com/2009/07/19/lunar-lander/
Copy lunar-lander.py's source code and paste it at https://micropython.org/unicorn/
Then replace the constant burn rate in line 55 with interpolated input from the virtual slider, with some delay from a basic moving average filter (for instance with window of n = 3)
Be careful: Do regularly copy-paste your code to an external editor. Just like real-life microprocessors, this emulated MCU can crash and take your code with it.
It also helps to refresh the page every now and then, to "reset" the emulated MCU.
