Hi
I have follow this guide many times to create a standalone arduino.
It works very good.
That I do is that I start with the guide to create a basic start so my atmega328 have power and working, after that I start add the button and LED and that.
Now I have a little problem, I was thinking about make a LANC remote with this guide
but that have connect the power to Arduino VIN?
My question is that instead to connect all my positive (+) to a power source like I do in my first guide, shall I connect them to the +5 in the ring like a VIN and the ground to the ring ground in the plug?
I mean is arduino VIN similar to the VCC, AREF and AVCC that I connect to my power source?
I can guess that ground go to the ground but the other I'm not sure??
I hope someone can tell me if that is right or wrong?
cazz:
hmm ok so I have to maybe scale down if I going to use it on VCC, AREF and AVCC ?
I mean if I read the scheme right the plug can have 5-8v??
If by "scale down" you mean ensure your input voltage is 5V, yes. If you have an external 5V source you can use that without regulation in the same way as the 5V is drawn on the Arduino design directly from USB. Be sure to refer to the datasheet for the particular ATMega you're using for the range of acceptable voltages allowed at VCC.

hmm ok, then it is a good idea to use a 5v voltage regulators to be sure.
