Explore the string library basics by declaring variables, locating substrings with find, measuring length, converting to lowercase and uppercase, extracting substrings, and concatenating strings to produce results in the console.
Wrap functions and variables in a table that serves as a namespace, load it with require, return it as the module, and expose a say_hello function that prints hello world.
Wire the motion sensor to the development board, adjust delay and sensitivity, and read its digital output that rises to about 2.3 V on motion and stays low otherwise.
Learn to connect a motion sensor to a microcontroller and drive an LED with a 220 ohm resistor, turning it on for a set duration when motion is detected.
Implement mqtt as a publisher and subscriber for a motion detector, using topics motion detected and elodie state to send data to a cloud broker.
