iCircuit is the premier iPad and iPhone app for designing and experimenting with circuits and Arduinos. Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.
You use it as you would any CAD program: you add elements, connect them together, and set their properties.
But iCircuit is unlike other CAD programs because it is always simulating. It's just like working with the real circuit. You do not stop to take a measurement or spend a lot of time configuring reports. Instead, you just play with the circuit as you normally would, with the power on!
There are over 300 elements you can use to build your circuits. The app has everything from a programmable Arduino, to simple resistors, to switches, to MOSFETS, to digital gates.
The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The scope can simultaneously track many signals over time and features a touch interface to control the total time displayed and stacked and unstacked modes to easily compare signals. The scope can also display the Fourier transform of any signal so that you can see the performance of filters.
Supported elements include:
• Programmable Arduino using a subset of the C programming language
• Programmable PIC controllers using assembly language or hex files
• Signal generators, Voltage sources, Current sources, and Dependent sources
• Resistors, Capacitors, and Inductors
• Manual SPST/SPDT and DPST/DPDT Switches, Push buttons, and Relays
• LEDs, Diodes, BJ Transistors, and MOSFETs, Thermistors
• Triodes and tetrodes
• Audio simulation with Speakers, Microphones, Buzzers, and LEDs
• DC Motors and Servos
• ADCs, and DACs
• Logic gates: AND, OR, NAND, NOR, XOR
• JK and D Flip-flops
• 180 digital ICs from the 4000 and 7400 series
• 78xx and LM317 voltage regulators
• 7-segment and matrix displays
• Antenna with simulated AM and FM signals
You can also create sub circuits to introduce new elements and componentize your designs.
No matter your skill set, you'll be playing with circuits in no time with iCircuit.
