Description

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.

Not really what I wanted from an app

ConHKL on

Doesn’t have options that I wanted as a sparky and it drains a lot of battery. Not worth it imo.

Good portable simulator but could do with some improvements

321Scatter on

It's great to have a portable circuit simulator, and for the most part I like how icircuit does things. But (there's always a but) The oscilloscope's measurement cursors needs work. Normal cursors have vertical and horizontal axes locked together at a point which follows a trace. These are weird and I'm not even sure what the up and down slope symbols represent. The gauge device seems to be DC but it doesn't read DC properly in the presence of AC. The incorrect measurement needs to be fixed and it'd be much better if it had options to measure DC and RMS separately. Even better if it also had a resistance measuring function. Then call it a multimeter. The meter function seems to only measure RMS. Additional DC (average) values would be useful.

This is a great App with allot of potential

Revanvulkar on

There is allot of room for potential, growth and development with this and I use it for work daily as an auto electrician, I really have allot to thank for this app and if you have the time to try it I suggest you do

Bit clumsy and insensitive

Rpeem on

Very clever and enjoyable .. but a t times a bit fiddling.. Extending a wire, it goes all over but where I want..Why?

ohmmeter

Baldy97 on

Struggling to find a way in the app to calculate the resistance across two points

Buggy

President.Evans on

It’s weird, when I click on the ‘+’ button to add a new circuit, it just doesn’t respond. I’ve resorted to uninstalling and reinstalling it so I can get the default circuit, so I can actually edit something and get it working.

It supports you with a link to Wikipedia

Tate Causea on

Very limited app, it should be free Not many components in library Confusing to use Gives you links to Wikipedia - useless I just wanted to do simple audio builds but it’s so limited I can’t even do that

Scope doesn’t work!

Logan81@ on

Scope icircuit doesn’t work! EveryCircuit is better ! Don’t lost time and money

Does not save

Vegano275 on

I bought this app knowing it was good to use on a Mac. I bought it now for my iPad Pro 12.9 and it has a major major issue. Majority of the time it will not save your work. Hours of work will be not saved and you can imagine how frustrating this would be. Don’t purchase until they admit it’s an issue and release the fix.

Options have no back button or done

Genie77 on

New update is missing button to return to diagram from options. Also the arduino code section does not scroll, and suffers same problem not being able to exit back to diagram forcing me to exit and force quit app.
