Hey,
I'm new to working with arduinos and I've been trying to upload sketches but i always get an error that says
avrdude: verification error, first mistmatch at byte 0x0000
0x62 != 0x0c
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch
Even with the default blink sketch, it doesn't upload.
Any help would be much appreciated, thank you.
You need to say which model of Arduino you have (Uno) where you bought it from , which type of computer you have , where you downloaded the software from and which version it is .
Also how did you up load ? Using arrow on the tab. ?
@samstrass , looking at the brief information provided, your sketch is compiling correctly, but it seems that there is a problem with the IDE (actually avrdude) communicating with your Arduino.
As @hammy says, more details please.
Sorry, I'm new to this.
I got it from an Egeloo kit (UNO R3). I have a windows 11 computer (built), I downloaded software off the arduino website (v1.8.19) and I'm using the upload button on the top of the window (below the toolbar).
yeah, there's only one board that I can select and the IDE is set to the UNO.
It turns out the board was dead. I got a new Arduino UNO R3 and it works.
