Program all the things - How to develop IoT devices using MicroPython
summary
Builds a Wi‑Fi IoT pet using MicroPython on ESP8266 dev boards (Adafruit Feather Huzzah, Wemos D1 Mini, NodeMCU), a 12‑LED neopixel ring, SSD1306 OLED, button and piezo buzzer. Uses the interactive REPL, ampy and webrepl to iterate, PWM for tones, and uMQTT for publish/subscribe. Notes one ADC pin limit on ESP8266, drives ~30–40 LEDs safely from a single pin, and demos a working web server and MQTT button events — prototype survives packing poorly.
