This tutorial shows simple technique of how to control an RGB LED with an arduino with step by step instructions and detailed circuit schematic. Schematic and sample code can be found at arduino lesson 13 at http:www.toptechboy.com
This tutorial is a simple and easy way to read Strings over the Arduino Serial Port. Also, will cover reading Ints and Floats.
This video describes how to make analog voltage measurements on the arduino using pins A0 through A5. A simple voltage divider circuit is set up using a potentiometer. The circuit schematic can be found on lesson 10 at www.toptechboy.com
This lesson shows how you can output analog voltages on the Arduino microcontroller. On the arduino uno you can do analog writes on pins 3,5,6,9,10,11. These are the pins marked with the squiggly lines. You can get more supporting information including code and schematics at our WEB site http://www.toptechboy.com
This arduino lesson presents a simple tutorial on getting user input from the serial monitor over the serial port. This allows you to interact with the user, and not have to hard code your parameters into your program. You can get the schematic and starting code at Lesson 6 at http://www.toptechboy.com
Arduino Lesson 3 introduces the concept of a for loop and shows how it works. The lesson centers around controlling two LED’s. Concepts of code documentation and comments are also introduced. See resources and full details at http://www.toptechboy.com
