+`GPIO-demo.py` is a demo using I2C to read data from a BME280 environmental sensor, and then display it on a SSD1306 OLED display.
+- It will be expanded with hardware PWM and digital pin input/interrupt code later.
 - All the install steps here (making the venv, `apt` and `pip`) are tediously slow on the MQ Pro.
 
 For the demo we need to install some dependencies via `apt`.
