"A Proteus is a program which is used to design, layout, and test printed circuit boards (PCBs). The Proteus contains a PCB layout or schematic design that includes mounting holes, wires, and device placement.
Running a circuit in Proteus:
1. Open the Proteus ISIS Schematic Capture.
2. Then, select the Component Mode from the left Toolbar.
3. Click On P ( P here is Pick From Libraries)
4. Add all the required components.
5. Place all the components on the workspace.
6. Then, wire up the circuit.
7. Click on the Play Button on the bottom left to start the simulation."
