Feel free to share that which you'd recommend having in your toolbox that which helps you develop your builds at hand.
For example, when it comes to Arduino emulators/simulators, what would you recommend?
Also which gems do you have when it comes to general electronic design/simulation?

My, still going strong, goto when it comes to electronic design is https://www.expresspcb.com/ , mainly because I've never really bothered checking out other, far better I might add, free software as such :)
