avrdude: stk500_recv(): programmer is not responding + avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x47
I had the same exact problem and fixed it, just by molding the two reset pins on the arduino together. Just check if they are properly connected as the error probably is caused by that. 



If that doesn't work, check the LEDs on the board. When you are uploading a sketch both RX and TX should be lightning up.
