Hello,please help me with my arduino uno,yesterday it uploaded a code fine then minutes later it stopped and started giving error when i try to upload.
The orange (L) light blinks then stops when i click upload then it gives error.
Please, show the errors you are seeing.
The Uno ships with a "blink" code installed. Applying power will make the "L" LED blink once each second. Pressing Reset will restart the board and restart the blinking.
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xff
avrdude: stk500_recv(): programmer is not responding
that is the error it prints
That means that there is a problem with communication between the Uno and your PC. It has nothing to do with the code to be uploaded.
Do you have the right board selected in Tools, Boards?
Do you have the right port selected in Tools, Ports?
Is the USB cable a known good data cable?

- TOOLS >> PORT >> (your port)
