Arduino Circuit Design Program

So I bought my first Arduino kit and it's quickly become apparent that I should really know more about electronics if I'm ever going to come up with my own projects. So I'm reading through a book on electronics and thinking there must be software that helps map out circuits. I've googled a few, but thought I'd get the opinions of people here. Is there a good (preferably free) circuit drawing and dare I say testing software (open source?) that people like? I see there are some open source projects and a few free ones from circuit manufacturers, but I'm not sure which one I should put time into learning?

Quote LTspice IV is a high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators. Game Yugioh Power Of Chaos The Final Duel. Our enhancements to Spice have made simulating switching regulators extremely fast compared to normal Spice simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. Included in this download are Spice, Macro Models for 80% of Linear Technology's switching regulators, over 200 op amp models, as well as resistors, transistors and MOSFET models.
