Hi
I am having a an issue with uploading a sketch to my arduino (atmega328 on breadboard)
I could upload sketches perfectly until my last upload when i added a delay() 
to the setup() and from here on i cant upload
I have attempted resetting manually, i also have a reset coming off my ftdi cable
I do have another arduino to reburn the bootloader if it comes to that
Any help would be great
Error message?
Binary sketch size: 450 bytes (of a 30720 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
The error message indicates that avrdude (the program used to upload) is unable to communicate with the bootloader.
Does your FTDI cable work with other processors?
It was working perfectly until i uploaded the sketch with the delay(500) in the setup() section of my code now for some reason it wont upload
EDIT:
Seems one of my jumper cables had a break in it, i replaced it and its working fine now 
Thanks for the assist 
Glad to know you have it working. Thank you for the follow-up.
