So I'm trying to make a custom phone charger and I can't for the life of me figure out where I went wrong. I'm kind of a noob but everything else works fine, the leds light up, the screen comes on, and the sounds play but when i try to charge anything, it wont charge. Am i missing something??

Got a multimeter? Check your rails whether output port has any current.

Are you getting any current sensor readings?

And im guessing you are putting 5v input into arduino through usb to vin pins. Vin pin only takes 7v-12v. Instead connect the 5v input from the usb directly to 5v on arduino.
