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

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.

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

Special thanks to:

• The MicroPython team, sparing me from having to learn C.
• enchant97 for the Max7219 library.
• JumpZero for making the CET time script.
