Hi all
I've tried my first Nano every project after several Arduino UNO projects.
I power the NANO and the circuit using a 9V 1A wall wart and the PC usb cable.
In this configuration everything works just fine.
After I've programmed the NANO I've tried to remove the USB cable and the power led on the board turns off.
2 GND pins are connected.
Vin pin is powered by 9V
The rest of the circuit is powered by 5V using a 7805 linear voltage regulator.
I don't know what's going on since it's my first NANO project.
Do I have to connect the 5V pin? I thought it was a power output.
Can anyone help me?
p.s. I've noticed that the circuit is working just fine IF I connect the usb port to a power supply (the PC is not needed: it's needed usb power... is it normal?)
