I am a total newbie, just built an Ardweeny. I hooked it to the computer via a Solarbotics USB to TTL adapter, had to install FTDI drivers on my MacBookPro running OSX 10.5.8. After install I was able to connect and upload to the Ardweeny once but now when I connect it I get
"Serial port /dev/tty.usbmodem621 not found. Retry the upload with another serial port?"
I have an Uno as well and it connects no problem.
I have been looking around for a solution but haven't found anything that works. Help me please!!!
