I pulled my Arduino Mega 1280 out of the closet after a year (i purchased it and never used it) and have a few questions.
What is a bootloader? Do you need one to upload sketches using the arduino software? I have successfully uploaded sketches using the arduino software, does this mean i have a bootloader? Help!?
What voltage/current do the digital pins accept as input? Could i put 6V over them? What voltage/current do they output?
Also, what voltage/current do the analogue pins accept as input? Could i put 6V over them?
