Basics

• An introduction on what is Arduino and what I can use it for?
• The Arduino Uno Board anatomy.
• What is the Arduino Software (IDE) and how to change the default language? What is a Sketch and how does it work?

Microcontrollers

• Digital Pins: How the pins work and what it means for them to be configured as inputs or outputs.
• Analog Input Pins: Details about the analog-to-digital conversion and other uses of the pins.
• PWM: How the analogWrite() function simulates an analog output using pulse-width modulation.
• Memory: The various types of memory available on the Arduino board.

Do you want to develop further the Arduino Hardware, or just build an Arduino on a breadboard? Check out the Hacking section.

Programming

• Language Reference: Discover the what each term of the Arduino code language means.
• Variables: Understand how to define and use variables in a Sketch.
• Functions: Learn how to define and use functions in a Sketch.
• Library: Using and installing Arduino Libraries.
• Cores: Need to add a new board to the Arduino Software? Install the relate core and manage it.
• Vidor HDL basics: Learn the basics of FPGAs programming language.
