Micropython on MicroControllers
4 likes977 views
This document provides an introduction to using Micro Python on the ESP8266 microcontroller board. It discusses Micro Python as a Python 3 implementation optimized for microcontrollers. It then covers setting up the ESP8266 dev kit hardware and connecting it via serial to load and run Python code. Examples are given for blinking an LED, reading analog data to control a night light, connecting to WiFi, using the web REPL, and creating a basic IoT setup to send sensor data to ThingSpeak. Contact information is provided for questions.
