Arduino Uno R3 Unboxing

Today’s unboxing is the Arduino Uno R3 Microcontroller. This particular model is the R3 or Revision 3 model, which is the newest revision of the Arduino Uno available at this time and is packed with lots of features.

I plan on using the Arduino to turn on lights, motors, and monitor sensors on my electronics projects.
