Hi all..i'm shobha..new to this arduino microcontroller...my error whuile uploading code to the arduino uno is " avrdude: stk500_getsync(): not in sync: resp=0x00 " .... i know this may be a basic question..i even looked into the forum where lot of options was given to tackle this problem but none is working fine with me. I have windows 7 operating system. i tried the following options :
re installed the driver
checked for the correct com port i.e; tools->serialport
even tried with reset button of arduino while uploading sketch
4)made sure the usb cable is plugged in rightly
5)disconnected all cables and pins
but none is working fine...please somebody help me....
you should try the manual reset (press reset button util you upload sketch), it is very hard to do because you have to leave the button in the right time.
if you have another working arduino you can have some practise with it, just look how to disable autoreset with a condensator.
Do not use USB power. Power up the Arduino before connecting to the computer's USB port. Powering-up the Arduino while at the same time connecting to the USB port does not allow the Arduino's circuitry and software time to settle to a state that will allow it to negotiate with the computer's USB port.
When you get the 'not in sync' error, disconnect and reconnect the USB port.
