Arduino Powered Usb Phone Charger

About: Crazy about llamas!

I love tinkering with everything!

our power bank stopped charging and I took a screw driver and popped it open .

Step 1: Have a Broken Power Bank ??

you will need:

arduino uno r3

usb hub (from inside a power bank ) with 3 usb ports mine also had an led array.

2 jumper wires

usb cable for arduino


and maybe pizza .

Step 2:

put one wire into the 5v pin on the arduino

an the other into the gnd pin under it.

Step 3:

tape the 5v wire on the positive terminal of the hub.

tape the gnd wire on the negative terminal.

Step 4: You Are Finished!

plug the arduino into your computer or a 5v supply and then plug your phone into one of the hub's usb ports

turn the hub on and it will charge your phone,lamp,power bank and many other things.
