Instead, you just play with the circuit as you normally would, with the power on! You do not stop to take a measurement or spend a lot of time configuring reports. It's just like working with the real circuit. You use it as you would any CAD program: you add elements, connect them together, and set their properties.īut iCircuit is unlike other CAD programs because it is always simulating. It is the perfect companion to students, hobbyists, and engineers. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. ICircuit is the premier iPad and iPhone app for designing and experimenting with circuits and Arduinos.
