I am looking to build a standalone arduino board, meaning I prototype something on the arduino, program it, then take the chip and place it on a seperate board and use it that way. Mainly it will be used with LEDs, so nothing too extreme. I found this on instructables: http://www.instructables.com/id/Standalone-Arduino-ATMega-chip-on-breadboard/
Would that be the way to go? I realize that isn't the best place to get ideas. If not, can anybody point me in the right direction, like what parts I will need, or a diagram. I will need a few of these boards, but don't want to buy a new arduino board everytime. Not exactly sure what to call this, but hopefully someone will understand what I mean. Thank you.
So this would be good to use as a basis to draw up a schematic and get some boards made which will permanently hold the chip I program along with the other parts (LEDs, pot, etc.)? I plan on using a 12 volt battery. That 7805 regulator going to be ok with it?
Can I eliminate some parts? I see some that I won't need. Could someone let me know if by eliminating these parts this would still work?
In the pic "LED", can I eliminate the LED, resistor, and black wire to ground? Don't need that LED.
In the pic "Add a reset switch" can I eliminate the tact switch, black wire going to ground, & black wire going from the switch to pin #1? What about the resistor, does that need to stay? Don't need the reset switch.
In the pic "LED on Arduino Pin 13", can I eliminate the green LED, resistor, and red wire? Don't need this LED either.
Power however you want.
7805 can run pretty warm if you are drawing a lot of current. Give yourself room to add a heatsink, or use a TO-220 type package that you can slip a heatsink onto.
