Hello friends, I hope you are doing well. This is the second tutorial in our series on how to create a Proteus library. In the previous tutorial, How to Create a Proteus Library: How It Works Behind the Scenes , we looked at what a library part is made of: the symbol, the pins, the properties, the package, the index and the simulation model, and at what Proteus does with them when you press Run. Today, we start building our own part, and we start the way every good component starts: on paper, before the first line is drawn. Our topic is how to design a new component in Proteus . Our running example is a Traffic Light Module , a small board with a red, a yellow and a green lamp that an Arduino switches through three pins. In this tutorial, we will decide what the component must do, choose b ...
