Best way to test an Arduino sketch without uploading to the board?

[CraigH]

Hi
What do you think is the best way to test an Arduino sketch without uploading to the board?
ie. What is the best piece of software available?

I’m currently writing an Arduino sketch and it would be very usefull if I could test it without having to upload it to the actual Arduino board, particularly because I’m writing the sketch at home and I only have access to the Arduino board once a week.
I’ve seen a few solutions out there but they all seem to complicated for me (a very beginner in Arduino coding), so which software would you recommend?
It would be useful if I could change the inputs in real time and observe the outputs from the pins.
Thank you!
