Hello- I am a beginner that just got the Arduino Uno R3 starter kit. I installed the Uno and completed the first 8 projects without a problem. Then, one day I pulled the Arduino out of the box and it would not accept an uploaded project stating the following error:
avrdude: verification error, first mismatch at byte 0x0000 0x62 != 0x0c avrdude: verification error; content mismatch
1) Arduino is recognized by my Windows 10 laptop on Com3 2) When I plug into USB, the green "ON" LED lights solid and the orange "L" LED lights solid 3) When I press the reset button, "L" blinks very fast repeatedly, then stays solid 4) When I attempt to re-burn the bootloader, I get the following error:
avrdude: usbdev_open(): did not find any USB device "usb" Error while burning bootloader.
Any help with troubleshooting this problem would be greatly appreciated!
