This is my second attempt at creating a PCB and have a couple of questions on my schematic. Basically this is a bare Arduino setup with two LEDs, an RF receiver, and some pins to program it with my FTDI cable. Nothing more than that; I'm trying to keep this attempt as simple as possible.
1) The top right part shows a voltage converter and decoupling capacitors according to this breadboard Arduino article. My prototype works fine so I know I assembled this correctly on my breadboard but I'm not sure if I drew this properly in my schematic.
2) The "S2" push button on the top left (here's the actual one I'm using) has two legs that aren't connected to anything. Should I connect 1-2, and 3-4 together or are they ok the way they are?
By the way, if you happen to spot anything that's not properly done (even if it is cosmetic) I'd appreciate a comment. I'd like to learn as much as I can from this process.
