| ## Instructions | |
| 1. Based on the examples you've seen so far, write a MicroPython code that follows the instructions above. | |
| 2. You can use the [Vittascience simulator](https://fr.vittascience.com/esp32/?mode=code&console=bottom&toolbox=scratch&simu=1&board=basic-esp32) to test your code. | |
| 2. Click the "Grade" button to get a grade and feedback. | |
| 3. Make sure your code is well-structured and efficient. | |
| 4. When you're happy with your code, please upload your solution below to get graded. | |
| 6. Good luck! | |
