Hello friends! In this tutorial, we will explore the components and instruments available in Proteus ISIS and learn how to choose the right item for a circuit. Finding a familiar part name is only the beginning. We also need to know whether it has a simulation model, which properties must be configured, and whether the item belongs to the schematic, the measurement setup, or a later PCB design. This article continues our practical Proteus series after designing an LCD circuit with a PIC microcontroller . We will cover ordinary components, displays, motors, serial tools, and shift registers, then connect each topic to the more detailed tutorials already available in the series. My aim is to help you build a sensible test circuit instead of placing unfamiliar parts and hoping that the simula ...
