Hi,
I am currently building something similar to - YouTube
and it worked a while, but today it didn't work so I tried re-uploading the code, but I was greeted with this message:
avrdude: verification error, first mismatch at byte 0x0000
0x00 != 0x0c
avrdude: verification error; content mismatch
I tried looking for solutions but I can't seem to solve it.
I am using the l293D IC like the video and the chip in the UNO is the ATMEGA328P-PU
I think that I may have overloaded or fried an IC or the UNO chip.
Please help.
Thanks!
Virgo
