Uploading error
im having this error.. a common one
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
when i click on upload the led on pin 13 blink twice and the rx too after,
during the upload nothing blink and when im receiving the error the pin13 led blink once my com ports are goods and i have a seeeduino board...
Check if you have the right FTDI drivers installed and than restart the computer 
It worked for me. Had the exact same error: seeeduino on Vista (i assume you have Vista too). Have to run ***.bat, the arduino.exe wouln'd start.
Now it works great. I tested a servo and a blinking LED, but have to search for some software examples of a servo and LCD display driving that doesn't use delay() function, since i want to display different data including time in real time on the LCD.
