I'm new at Arduino, infact this post is mostly about what parts I should buy to get started.
Here is what I wish to accomplish: I want a door to unlock when I enter a password on a website.
I know that I'll need an Arduino-board and an Ethernet shield, but several variations exist, and I don't have the knowledge to choose between them, so suggestions are welcome :-)
The door-lock requires a 12v DC signal, so I'm think it'll need a relay to turn it on/off as I please. Does a pre-built relay-shield exist, or will I need to build my own? If so, I would like suggestions on what parts I'll need for that, perhaps even schematics on how to assemble it?
Once I have my hardware, I'm sure I can get the programming to work :-) If not, I've noticed that there are lots of tutorials out there, so I don't think that will be a problem. (Also this isn't my first time programming micro processors.)
But long story short: What would your shopping-list look like, if you had to complete this project?
