Basic microcontroller programming with Python
summary
A working water-level monitor built with an Arduino Uno with pySerial and pyFirmata reads an analog water sensor on analog pin A0 (raw 0–641), sends values at 9600 baud to a Python program that maps them to 0–6, and drives onboard LEDs: <=1 => blink blue, 1–4.5 => steady blue, >4.5 => green. The Python side uses a VPython cylinder and label for a live virtual gauge, requires the Arduino IDE sketch uploaded first, and the demo runs end-to-end.
