Hi, i have been uploading programms like normal, but a few days ago after I just changed a little delay, the Arduino IDE had an error saying: avrdude stk500_getsync() not in sync resp=0x00. I am using Windows 10 and I have tried to use a different PC, but it shows the same error.
PS I also checked my board and com ports, they are correct, and when I hook reset up to ground, and Pin 0 to 1 the L-LED lights up, but the serial monitor doesn't echo what I'm typing.
Thank you in advance
