 Arduino® boards are mainly based on two families of microcontrollers: **AVR®** and **ARM®**. While AVR® family microcontrollers are based on the Harvard architecture model, ARM® family microcontrollers can be based on either von Neuman or Harvard architectures models. The following table summarizes Arduino boards microcontrollers architectures:

 Flash memory on Arduino® boards can be measured with the help of the Arduino IDE. As stated before, Flash memory is where the application code is stored; **the Arduino IDE reports Flash memory usage through its compiler output console** to let developers know how much Flash memory resources are being used.
