I have already shared two Arduino libraries for Proteus and they are also quite good but now I have thought to design them by myself in Proteus, which was quite difficult and literally it took me weeks to figure out How to add functionality of a new component in Proteus. In today's post, I am going to share Arduino UNO Library for Proteus. Update: We have created a new version of this library, which you can check here: Arduino UNO Library for Proteus V2.0.
