The schematic serves as a ' virtual prototpye' for the firmware and it's quick and easy to make changes to either. This brings you total freedom to experiment with diverse ideas and to discover the optimal design solution for our project. Now open your Proteus software and search for PIR Sensor, you will get total four models in it.
Proteus Virtual System Modelling (VSM) has mixed mode SPICE circuit simulation, animated components and microprocessor models to ease co-simulation of complete microcontroller based designs.
PIC microcontroller Basic connection circuit.Getting Started with PIC Microcontroller.It is good to have the following knowledge before going to PIC Simulation This article dealing with the most powerful simulation software the Proteus Design Suite Version 8. It is possible to play with your microcontroller just as in real world.
