Arduino Information

My arduino was bought at a swap meet, with no manual.  To learn about it, I did some web searches.  In the process, I found some interesting sites:

To start:
   www.arduino.cc  The Arduino home page!  Click on the link for "learn Arduino".   This page explains how to set one up.  (What software to install, etc.)  There is a list of arduino boards in the upper right corner.  Clicking on the name of your arduino board, will take you to a page with more setup info for your Arduino board.

Arduino Lessons:
  http://www.toptechboy.com/arduino-lessons/  I like the way he describes things here.  Made it easy to understand how to setup a circuit and write a simple program to control it.  Very cool!



Arduino Libraries
  https://www.arduinolibraries.info/libraries  A cool site with links to lots of libraries for the Arduino.

Infrared control
  https://learn.adafruit.com/using-an-infrared-library/sending-ir-codes  Setting up an infrared circuit.

Decoding the old Lego Infrared communications
  http://ofalcao.pt/blog/2017/decoding-old-lego-infrared-protocol  He has quite a bit about the old Lego infrared communications.

Arduino Bluetooth Basics:
  https://www.hackster.io/user206876468/arduino-bluetooth-basic-tutorial-d8b737  Here he shows how to setup an HC-05 Bluetooth Module to an arduino, and a simple programming to control it from a smart phone.

Using the Arduino Uno and HC-05 Bluetooth Module:
https://www.hackster.io/tenerdz-group/using-the-arduino-uno-and-hc-05-bluetooth-module-576f3d
  I like this one more than the previous circuit.  Here the Bluetooth module has a simple voltage divider . (A pair of resistors to limit the voltage to the HC-05).


With this info in hand, I can start designing my Don's Electronic Thing!
