Hi, I am new in arduino world. I am using UNO R3 with Windows 8.1. It was working fine and all of a sudden it is having problem in uploading code to the board. The error it is showing is:
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x64
Can anyone sort out the problem? It is not upload any example code as well.
