Have the starter kit, and successfully made it through tutorial Lesson 3. Much fun with blinking lights. When attempting to upload the first sketch in Lesson 4, received the error code:
avrdude: stk500_getsync(): not in sync: resp=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x5
Attempted to re-upload earlier sketches, and get the same error.
Potentially useful data: Duemilanove, Mac PPC OS 10.5.5, Arduino 0012, FTDI Driver 2_1_10. Mounted LED on board stays lit; TX light blinks about once per second. Have unplugged/plugged in several times, restarted the computer, and reloaded FTDI Driver, all without success.
Thanks in advance for all assistance offered.
