I have a arduino uno and wanted to add the watchdog library to reset the device if it locks up. However i can not locate the library as its not on the program and i cant find it online. Can some help with this please.
Somebody with more experience should answer it better than me, but I think you have to flash a watchdog enabled bootloader.
They're located on your_ide_path\hardware\arduino\avr\bootloaders...
There are a lot of tutorials on how to properly burn a bootloader!
