SleepWise

A clock that counts down until your bedtime, reminding you of the little time left.

What's this?

This is a simple project of mine where I plugged a MAX7219 to an ESP8266 NodeMCU that has MicroPython on it. The main.py file should be edited to customize the counter to your needs. I have implemented aiorepl into the library for debugging. Sometimes it works, sometimes it does not. The script uses Central European Time.

How to use

1. Buy the necessary hardware.
2. Flash MicroPython onto your ESP8266.
3. Install mpremote for REPL access and file operations.
4. Clone my repository, edit main.py to fit your needs.
5. Transfer all the python files with mpremote, like mpremote cp main.py :.
6. Modify boot.py in the micropython root to include something like this:

try:
    import main
except Exception as e:
    print(f"Error in main.py: {e}")
    print("Entering safe mode - REPL remains accessible") # This way REPL doesn't lock up.
