I followed this tutorial here: http://arduino.cc/en/Tutorial/ArduinoToBreadboard and was successful making my own little Arduino from a bare chip. The process wasn’t that bad but doing the whole deal with just an Arduino (No stand alone programmer) requires pulling the chip out of the Arduino socket to load sketches onto a bootloaded chip.
Anyway, I got it in my head to make an Arduino replicator shield that would make it easier to pull the chip and perhaps prepare new ones without too much fiddling. I have several projects figured out on a breadboard that I would like to make permanent using bare chips.
I know the best route would be to use another programming option like a standalone programmer or a teensy or some of the other methods suggested by knowledgeable forum members but I’d like to fool with this idea some.
Here is where I’m at now:
I’ve just relocated the chip to a ZIF socket on a proto shield. It functions just like it did before but now the chip is just easier to pull and I have room for a second ZIF for (maybe) burning the bootloader to bare chips using the Arduino as ISP and then I could just pull the original chip and put the bootloaded one in it’s place and upload sketches to it.
I had looked at some folks projects where they just pressed a ZIF socket into the DIP socket on the board but I was scared it would screw something up…
For now I would like to relocate the TX/RX leds to the shield plus put an LED on pin 13 on it as well. I’m not sure about bringing the RX/TX lights up so any help would be appreciated.
Also, any other guidance on how to proceed would be most welcome!
