Here’s a novel application. Supecapacitor has developed a circuit simulation project using Arduino-Processing. As he describes it:
“SuperScope is a circuit simulator app for representing and calculating analog circuits.
What’s so cool about SuperScope is the ability to actually import circuit components (via Arduino Serial) into the program where you can physically manipulate them.
Arduino tests for the value of the component (a capacitor, inductor, resistor, or waveform of specific frequency) then sends the data to Processing. Imported components can then be plugged into circuit schematics. SuperScope builds upon the mission of Arduino, the interface between hardware and software, analog and digital.
SuperScope provides the user with three graphical representations of the circuit. The first is the basic frequency-domain plot; graphing voltage vs. frequency. The second is the vector diagram; depicting the phase and magnitude of the output.
The third is a phasor; a dynamic, analytical representation of the output’s phase and magnitude relative to the input’s.”
