Error "avrdude: stk500_getsync(): not in sync: resp=0x00" How to get Rid of it

when the error avrdude: stk500_getsync(): not in sync: resp=0x00 comes in screen


it is usually comes because of selecting the wrong com port in the arduino tools menu
we can usually see which port we connected by the following method

go to the control panel --> Hardware and Sounds --> device manager --> Ports(Com & LPT)


and set the correct the com port in Arduino Tools Menu. OR may be due to selection of other Arduino Board
