This question already has an answer here:
I've been getting this very common error on my atmega328pu circuit.
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x83
Some things iv'e tried are:
- Restarting my comp
- Reuploading the bootloader
- Redownloading old version of arduino IDE
- Using an FTDI chip and placing the chip inside an Uno
After I bootloaded the chip I was able to upload a blink sketch. Then the next time I tried I got this error. Anyone know what could be up? This is driving me crazy!
