The document discusses creating a DIY smart lighting system using MicroPython and ESP8266 microcontroller. It covers the basics of smart lighting, components needed, setup instructions, and how to control the system remotely via MQTT and IFTTT. Additionally, it encourages creativity in design and application for everyday use.

What We Will Do

14. MicroPython
14
● Python programming language that is optimised to run on
microcontrollers.
● Created by Damien P. George at 2013
● Learn more https://micropython.org/
● Micropython is Installed on your microcontroller instead of
your computer
● Support REPL, Run from file and standalone.

15. Getting Started (on Ubuntu)
15
● Install Tools = [ esptools.py, Adafruit MicroPython Tool (ampy),
Serial Terminal ]
● Download images (http://micropython.org/download#esp8266)
● Install
○ Plug in microcontroller to your computer
○ $ esptool.py --port /dev/ttyUSB0 erase_flash
○ $ esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash
--flash_size=detect 0 esp8266-20170108-v1.8.7.bin

16. Getting Started (on Ubuntu)
16
● Open Serial
Terminal
● REPL active
if not blocked

17. Getting Started (on Ubuntu)
17
● Files on MicroPython
○ $ export AMPY_PORT=/dev/ttyUSB0
○ $ ampy run main.py # run main.py from computer in microcontroller
○ $ ampy ls # Checking file(s) on microcontroller
○ $ ampy put main.py # copy main.py from computer
● Hierarchy:
○ boot.py
○ main.py (if exist)
○ REPL

24. MQTT - Most Popular Pub-Sub for IoT
24
Brokertable-lamp
room-lamp
publish table-lamp (255,0,0)
receive table-lamp (255,0,0)
receive table-lamp (255,0,0)

25. Adafruit IO Topic Format

● Make Your Own
● Design your favourite case
● Use it for your daily
● Be creative

34. What Next?
● WiFi Setup Over The Air - Using Pico Web
● Digital Input - Physical Button
● Sensor Input (ADC, UART, I2C, etc) - Light Sensor,
PIR Sensor, Infrared Sensor
● Actuator Output (PWM) - Electrical Motor, Servo,
etc
