I am fairly new to the Arduino and now I am collecting all the stuff I need for basic trying and experimenting.
Just a basic question arises now: To program and operate the UNO, I need to connect the device via USB to my Notebook.
I’ll use a breadboard for the experiments with the parts and this needs to be powered too.
I got one of those breadboards mounted on a plasticplate with 2 terminals ( blue and red ) for 4mm banana jacks. Here I would like to connect a 9V or 12V stabilized DC power supply to provide power to the circuit.
Are there any concerns programming the UNO through the USB and having on the other side the circuit powered with 9 Volts.
Then I need to unplug from USB and provide 12V to the circuit on the breadboard …
This all sounds not right to me, so I would like to ask you guys with lots of experience.
