You can download the Arduino Proteus Library using the link below or the button near the end of this tutorial. The Arduino Proteus Library is based on the AVR microcontroller’s model that comes with the Proteus ISIS simulator itself, we just need to install an add-on library to have a couple of Arduino boards models included as well as some sensors that you can use later on for your Arduino Projects Simulation.
I’ll show you how to install the add-on Arduino Proteus Library and use it for simulating Arduino projects. Please, be advised that you first need to have installed Proteus ISIS on your computer and your license (time-limited free, student, or whatever) can simulate microcontroller projects (AVR, PIC, etc).
