Hey all
Hope you are all good today.
I would like to know which device in the Arduino range I need to use to make a project standalone. I have a sketch which works fine, but want to put the code onto another device so I can get the use of my UNO back but finalize the project so it will continue to work without the UNO.
Any advice would be appreciated.
Don
Is this where we remove the cpu ic from the UNO and prog a Arduino mini to run by itself??
Atmega328P-PU for a DIP

Also need 16 MHz crystal, two 22pF caps, 10K resistor, four 0.1uF (100nF) caps.
If are using a reset switch, then a 1N4148 diode as well.
How are you powering it? 3 AA batteries? 5V switching regulator wallwart?

Promini has all that as a little card.
Can also buy a bare board and some components and make up a card

You can use your UNO board to program an external Atmega chip:
http://arduino.cc/en/Tutorial/ArduinoToBreadboard and then set up the stand alone project.
Don't know what you need, but for a low expense (less than $10) you could use a nano clone.
What do you really need/want?
There are good instructions here http://arduino.cc/en/Tutorial/ArduinoToBreadboard including instructions about using the Atmega328's internal 8MHz oscillator which reduces the number of external components. I have an 8MHz version running happily to control my fridge.
