Hello people, I have a question regarding the input of Genuino.
So far I have provided 5V from my laptop's USB which is 5V. Thus, I thought it could be the same if I provide 5V from a power bank that I charge my smartphone. The power bank is 5V/1A with a capacity of 4400mAh. Would it work this way?
Second, would it be safe to provide 9V battery at the input of Arduino and run the program normally?
I looked for documentation (explaining how the ports and interrupt work) but the only thing I found is the Eagle document, the microcontroller's port sketch and some examples at the "File" menu of Arduino. Isn't there a detailed document (pdf) explaining the interrupts etc?
Thank you in advance.
