Example Sketches

The Arduino IDE comes with Built-In examples, and they are all available under the Menu Item 'File' in the upper left corner of the IDE. The current example highlighted in the image above is the 'Blink' sketch, which will be discussed in more detail in the 'Writing Code' section of the Arduino tutorial. 

There are a wide range of different example sketches that teach the reader about some of the many capabilities of an Arduino.  Examples include using the analog ports(there are 6 on an Arduino Uno: A0-A5), Reading various Sensors, controlling both the duration and intensity of an LED when lit, and Communications. As we will see on the next page, communications is extremely important because it allows the user to obtain information from the processor for various states, values, etc.
