How to get my portable charger working? Answered
Im building a portable USB charger but for some reason my phone ins't showing any sign of the charger being connected. It used to show when it was connected but I cant figure why it isn't now. I measured the voltage going to the USB its 5v and the two data lines are 3v. I used 33k and 22k for the data lines so i can get 2v to each line. Is there anyway someone could kinda assist me on making this circuit on a breadboard i'm kinda getting confused on how to set it up. Also is my 7805 going bad because sometimes the input voltage is the output voltage.
