Sensor: Humidity (linked list)



Plans test DHT11, DHT22 and SensePi Temperature and Humidity sensors and compare

 https://github.com/netikras/r-pi_DHT11/blob/master/dht11.py Works as is! Code is Python 2, but works under Python 3 only changing print statements.

Info on how the values are read from the sensor, but Python code is broke and not even close. Interfacing 
Temperature and Humidity Sensor (DHT11) with Raspberry Pi (C, wiringPi)

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...
