I was wondering if there is an ardino "simulator" where we could upload our code and attach components in a 2d environment. I thought it would be awesome for prototypes since you could modify on a computer and then build the final version. Does anyone know of any such thing?
Maybe this isint in the right area but tell me if it isint and i will move the post accordingly.
Thanks
it struck ME as a good idea... 
but then again im a noob.... :-/
This has been up some times before, and I agree that it is a good idea. But, it takes only a few seconds to upload to the arduino so the gain would be minimal.
I've actully thought about making a simulator with C++ and SDL/OpenGL, but this is too much for a one-man-team, so it would be something that I would've needed assitance on making. Maybe there are someone that would be interested in sharing some ideas?
I think it would be a good idea but mapping/emulating all the op codes etc would be a pain, especially for EACH device.
It may be something for the future but for the mean time, I doubt you'd get my gain.
I think a better use of the time would be to create a unit testing framework, there may well be something like that when you use another IDE - I havent checked yet
I do not foresee simulating the opcodes, or registers or something like that. If one finds such information interessting, I suggest using the AVR Studio.
I have a simple app in mind. Just not simple enough for me to write on my own, at least no right now.
I imagine that you would paste a sketch into a simple text pane, and then press some kind of 'simulate' button, and then you get a picture of an arduino and now you see symbols for pins that are input, and a different cymbol for output. Maybe '-->' and '<--'.
And a color code for HIGH, LOW. such as black / red.
And, if user presses a pin with the cursor, he gets to choose input/output and high/low.
And that's it for the framework.
I would add possibilities for additional hardware to get contributed. By enabling a simple set of functions to enable 'scripting'. So one could make switches LEDs and maybe LCDs.
For instance:
onStateChange( byte pin ) : void
setGraphic( char* file ) : bool
setPinMode( byte pin ) : void
setPinState( byte pin ) : void
And a simple drag and drop graphical editor for making the circuits.
But, it might be true that it is a waste of time.
Ah sorry I misunderstood.
Considering the sheer number of various outputs and inputs (infrared rangers, Pots etc), providing a diagram would take a long time and just add to the work-load of library devs.
Still an interesting idea though
I think the typical user would be the eager beginner, that simply wants to see something happen from their modification of the blink sketch.
I remember that I searched for this as well , before I got the arduino, after I ordered it.

I'm kind of interested in this (could also allot for more streamlined prototyping for seasoned users, saving costs of ordering parts and such. (I'm no pro, but I imagine it could help)
Perhaps an arduino "emulator" that has an interface with SPICE to simulate pulses/signals (behaviors written in a tweaked Arduino IDE) and send them to virtual external hardware.
