Circuit Builder

This App is designed to be an introduction to constructing and operating electronic circuits. Intuitive controls and layout make Circuit Builder the perfect App for understanding the basics of electrical and electronic circuits.

Build your own virtual circuits using any combination of electrical components.
The easy to use library of components includes batteries, switches, lamps, resistors (fixed and variable), capacitors, fuses, circuit breakers, buzzers, heaters and motors. Connect components using virtual wires to make a circuit. Put the App into operate mode to see it work. You can even use virtual multimeters to measure voltage, current and resistance.

Circuits can be viewed and built in either component or schematic view.

The component library contains the following items:
