Hi, I’m working on a project where i need to monitor laptop battery percentage using arduino, I have searched online but did not find any article related to this. Does anyone have any idea how to read laptop battery percentage and send it to arduino?
It may not be with Arduino, and each battery may be used differently, [but you certainly can find something. You’ll have to do much research yourself. Many have some sort of SMB or I2C interface to transfer the state data.
