Hello friends, I hope you are doing well. Today, we are starting a new tutorial series on how to create a Proteus library . Proteus comes with thousands of parts, yet sooner or later every student and engineer needs one that is not there: a new sensor, a wireless module or a board of their own. Over this series, we will design such a part from the very first line of its drawing to a finished library that other people can install. Our running example will be a simple animated component, a Traffic Light Module whose three lamps light up when an Arduino drives its R, Y and G pins. In this first tutorial, we will not draw anything yet. Instead, we will look at the complete mechanism behind a Proteus library, because every later step makes sense only once you know what Proteus stores and why. W ...
