Did you ever get into a situation where you had to wire up two, three or more I2C sensors to your Arduino just to realize the limitation?

Improved serial debugging, with debug levels and simple software debugger, to see/change global variables, add watch, or call a function.

You'll learn what is the finality of standalone Arduino and how it is applied in real projects.

A small demonstration of the use of a web service and a data capture circuit via sensors.

Morse Code decoder that can adjusts to LED bright level and demonstrates how to implement timer interrupt.
