How much voltage does Arduino need
Arduino Uno and all many other big form factor Arduino boards are equipped with a standard 2.1mm DC power jack. Arduino Uno accepts 7-12V dec through this port and the onboard voltage regulator regulates it down to the required 5 and 3.3V.
Can Arduino Uno handle 12V
Yes, it is safe to power Arduino with 12V, Arduino has onboard voltage regulators that reduce incoming voltage to a safe limit of 5V. In fact, it is recommended to power an Arduino with a regulated 9V-12V DC supply through a DC barrel jack or Arduino Vin pin.
Can an Arduino output 12V
For most Arduino boards like the Arduino Uno, the maximum supply voltage is 12V so you won't be able to get 24V for example. You can also convert the 5V from the Arduino board to 12V power with a DC/DC converter.
How to power Arduino with 5V
The most common and easiest way we can power an Arduino board is by using its onboard USB connector. The USB connector provides a regulated 5V line to power the board's electronics. However, 5V from the USB connector can also power external components through the 5V pin that can be found in Arduino boards.
Can I use 9V battery for Arduino
The recommended range is 7 to 12 volts." I've found that using 9V works well. You can simply connect the + end of your battery to Arduino Vin and the – end to Arduino ground (fig 1).
Is 12 volt too much for Arduino
Can we give a 12V supply to Arduino If you put the supply into the Vin pin, then 12v is fine, most versions have a voltage regulator. The regulator is small, so don't take much power from the Arduino powered at 12v to avoid overloading the regulator. Don't take too much power from the I/O lines, or the 5v pin.
Can I use 12V 2a for Arduino Uno
With a 12V source, yes, current should limited to avoid overheating/shutting down the regulator. With a 9V or 7.5V source, one can do quite a bit.
Can Arduino run 12V DC motor
Since the Arduino takes a very small amount of current for it's internal circuitry, putting 12VDC on the Vin pin will be okay to power the Arduino.
Can I use 12V 2a for Arduino
With a 12V source, yes, current should limited to avoid overheating/shutting down the regulator.
Can I use a 9V battery on a 5V Arduino
Introduction: Powering Arduino With a Battery
If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts." I've found that using 9V works well.
Is 5V enough for Arduino Uno
Like already mentioned, you need a minimum of 5V to power up an Arduino. There are two ways you can do that. Use a 9V battery and connect it to the DC barrel jack.
Can I use 9V battery for 5V relay
Alternately,if the current rating of the relay is low, you can use a linear voltage regulator to convert 9v to 5v and then connect the relay.
How long can Arduino run on 9V
The 9V battery will power the Arduino for about 10 hours. The AA batteries would probably power the Arduino for 40 hours, but the voltage of the batteries will start to drain before that, so it might be less than 40 hours for 4 AA batteries.

Can I power Arduino with 9V battery
Yes, Arduino can be powered up using a 9V battery. There are several ways through which we can power an Arduino board and one is using a 9V external battery. Using a 9V battery we can make the Arduino project portable without any need for an extra power source.
Can I use 12V 2A for 5v 2A
No, You can use a 12V 2A Adapter with a higher current rating, but not one with a lower current rating. The device draws only the current it needs, but the power supply must be able to output the maximum current that the device requires.
Can a 5V motor run on 12V
You can not power a 5V motor with a 12V supply, unless you keep it submerged in liquid nitrogen to deal with the heat.
Can I power Arduino with 12V adapter
Some Arduino boards like UNO, MEGA and DUE, come with an AC socket that can be used to power the boards and to supply additional voltage if needed. A power supply adapter that provides from 7 to 12V (Volts) of DC (Direct Current) is required.
Can Arduino handle 15V
The Arduino Uno has a voltage in plug which matches it, and can take up to 15V. An on-board regulator converts the higher voltage input to 5V.
Can I use 12V 2A for 5V 2A
No, You can use a 12V 2A Adapter with a higher current rating, but not one with a lower current rating. The device draws only the current it needs, but the power supply must be able to output the maximum current that the device requires.

Is Arduino Uno 5V or 3.3 V
Unlike the Arduino Uno, which has both a 5V and 3.3V regulator on board, the Mini only has one regulator.
Is Arduino 5V or 12V
The regular Arduino "works" at 5V (some versions run at 3.3V). The board can accept 12V into the barrel jack and it goes-through a 5V regulator. The inputs & outputs are 5V (~5V is high or logic-1, and ~0V is low or logic-0). You can't feed 12V from a sensor directly into an input.

Can I power a 5V relay with 12V
12V will definitely damage the relay board. This 2 channel relay board requires about 200mA at 5V with both relays energized. I suppose the simplest solution would be to use a 5W, 6.8V zener diode connected in series with 12V to drop it to 5.2V.
