Arduino Nano with 9v power supply
You cannot usefully power the Arduino with a 9V supply using the "Vin" pin. The on-board regulator is capable only of supplying the ATMega chip itself; once you add another component it is not capable. You need to supply 5 V - preferably regulated - …
Seven Ways To Supply Power to a Breadboard
In order to draw more power from a 9V or a 12V power supply, a DC transformer can be used. DC transformers are quite common for providing 12V LEDs with power. Alternatively, they can also be used to supply power to breadboards. In comparison to USB DC-DC ...
How to chose between 9V or 12V (or others) DC power supply
I see a lot of devices working either with a 9V DC input or a 12V DC input, usually provided through a DC jack connector. I was wondering about advantages and/or inconvenients of both voltages. Indeed, most of the time, this input voltage goes almost directly ...
Can a 9v battery or AA batteries be used instead of a bench power supply?
Yes, batteries can be used instead of a bench supply. Keep in mind that batteries change voltage as they are drain, and cannot supply the same amount of current as any given bench supply. Plenty of examples online. As suggested, you can get a breadboard ...

9V Battery Power Supply
In this post, I''ll show a 9V battery portable power supply I made quite a few years ago by originally following this tutorial. This particular power supply uses a voltage regulator(LM317) to drop down the voltage and dissipate the energy as heat. This means it becomes inefficient at higher currents. So it is most useful to power things that …
How do you power arduino with a 9V battery?
