Many Arduino users are not unfamiliar with this error. It often appears in our experiments process .
Someone has made a detailed analysis for the error on the web, the analysis is as follows:
avrdude: stk500_getsync(): not in sync: resp=0x00
The problem was interpreted as a serial communication failure.
In the analysis, there are some reasons for this error:
- In the IDE download process, Arduino is not reset.
- Serial pin (0, 1) are in used.
- USB serial port communication is unstable.
- Bootloader is damaged.
- Used a wrong serial or board type (it can be corrected by choosing the right one).

Hello
I have this problem with I upload a program (ASCII example) to the Arduino (Uno). I have found that the problem dissapears if I remove the jumpers and upload again. Once the program is uploaded to the Arduino I reinstall the jumpers and everything works perfectly. I have checked that it transfers to Win XP Hyperterminal.
It is clear that there is some collision with the RX/TX of the Linksprite RS232 and the Arduino communication with the PC. Perhaps the problem would dissappear by using other pins of the Arduino for RS232 communication.
Best regards
