One question I have is which board I should select: the Mintduino doesn't show up on the list, so I've tried selecting most of the boards that have a 328 (which the Mintduino uses).
I have check to see that the FTDI Friend is showing up, so that makes me think it's working.
so I removed it and wired the breadboard's power rails to the +5V line of the FTDI Friend.
The FTDI shows up as dev/tty.usbserial-A4006Djt under the Arduino IDE's Tools->Serial Ports menu, which I hope means that it's been found by the OS and is capable of communication.
When I click the "Upload" control in the IDE, the Mintduino resets, but begins running the program that came with the AVR chip. I've double-checked the wiring from the ATmega 328 to the FTDI Friend and it seems to be OK.
