About iCircuit
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.

New Features
============
* Two finger dragging to replace the Pin
The Pin was an experiment in UIs to help you manage editing the circuit and panning around with just one finger. But that experiment has caused a lot of frustration in you the users. No more! iCircuit now uses 2 finger panning so you can quickly toggle between editing and panning using just your hands. This is only available on iPads and iOS 4 devices and can also be disabled if you love the Pin.
* Non real-time simulations
The circuit is still "always on" but now you can control the bandwidth of the fixed time step simulator to guarantee accurate results.
* 555 Timer, Potentiometers, and Text Labels
Thanks to your feedback (support@kruegersystems.com), two new elements have been added. The 555 should be great fun for students.
* External display (VGA) output on the iPad
Now you can hook the device up to external monitors, TVs, or projectors to share your circuits with an audience.
* RMS, Peak-to-peak, and Frequency now displayed in the scope
* 5 new examples thanks to Mike Acton
A dedicated user was kind enough to donate a bunch of circuits to making the Examples folder even more interesting.
* Tips on how to use the app can now be accessed form the Home screen
This is a large app with a lot of features. Tips are now here to speed up the learning process. You can also access these tips at http://tips.icircuitapp.com
Bugs Fixed
==========
* iOS 3.1 crashes and bugs have been fixed
There were a variety of errors encountered by users when using iCircuit on 3.1 devices, these have all been fixed.
* Better bounds checking on inputs (circuit size for instance) to prevent crashes
* Failing circuits no longer cause the app to fail to launch
* Send feedback button has been fixed on iPhones
* Performance improvements
