More on PICO and IOT comm

  •  Raspberry Pi Pico W for IoT Project Using MicroPython and MQTT [ A Complete Guide ]
    • Looks promising
    • Set-up
    • Tools->manage packages    search for sensor using....
      • Before installing Google and see if its something you really want to use
        • did for HC-SR04 and looks like it put sensor into a class... nice but need to read more

    • uses high fmq cloud mqtt broker HiveMQ (free service)
      • connect and publish using this
    • to subscribe Uses Red Node
      • googled rednode and raspberry pi pico and mqtt

Using a Raspberry Pi 4 A blinking LED is the Hello World for physical computing.  Raspberry OS allows many ways to do this.  Here are 3 ways to Blink an LED from the RPi 4. Figure 1: Blinking LED wiring on RPi 4 (from Tutorial 3 below) (gpiozero)   Blinking LED Raspberry Pi Tutorial 1 This tutorial is great not just for blinking LED but also intro to "Physical Computing": Getting started with Breadboard. Resistor labeling code diagram included. Using a multimeter to test power provided by the RPi Understanding basic circuit first not controlled, then controlled by the RPi. Using Python from a command window, testing basics 1 line at a time. Intro to import gpiozero , a pre-installed on RPi library with import for basic needs like LEDs and buttons. from gpiozero import LED import time led = LED(17)  # GPIO17 led.on while True:      led.toggle()     time.sleep(1)      (GPIO)  Bl in king LED Raspberry Pi Tutorial 2 Alte...
