I am trying to follow various methods of using the arduino uno as a programmer and loading a bootloader into an attiny 45.
I have got as far as loading the ArduinoISP sketch into the uno and compiling it.
(are there different ArduinoISP sketches? this one is written by Randall Bohn)
When I compile it it fails with ‘Serial’ was not declared in this scope any body know what I am doing wrong?
