Hi i made it!
it emits 5 volts from the left +- column and 9 volts from the right +- column of the breadboard is it ok?
I would like to know how many Ampere it can emit.
Thank you :)

Good job! :)

Yes, the circuit shown will put out 5v on the left and 9v on the right. The 7805 regulator for the 5v side will handle up to 1A, but that assumes that your 9v input can provide that much. If you are using the Adafruit 9v wall-wart supply, that is rated for 660mA.

Keep in mind there is a power limit also, which has a lot to do with your heat sink on the regulator (if any). Without a good heat sink you will likely not be able to do 1A. You calculate the watts by: (Vin-Vout)*(current). Then you can figure out your theta in degC per watt if you want to be really fancy...

5v is a good start for a usb charger. But different devices have different requirements for charging. Check out the MintyBoost pages for more information.
