Hi, I recently purchased some led strip lights which conviently are RGB lights, that I would like to control with my arduino. The setup are 4 pins
POWER| Green | Red | Blue | which connect to the remote reciver and controller. The Power in this case is 12V when comapared to the 5V that I am used to. I have a keystone arduino uno UNC, which from what I can reaserch online can facilitate 12V. I was wondering what the circuit would look like and whether or not my arduino will be able to be used in this senario.
Please read the how to get the most from the forum post. The post contains information on what we need to know in order to help you.
Please tell us what the Uno is to be used for.
Please post a link to the data sheets or other documentation on the LED strips, remote receiver and controller.
What else, besides the LED strip, will connect to the Uno?
Regard the reply from @ groundFungus
It is possible to power an Arduino UNO with 12 volt, on the Vin pin.
However there's no capacity to power other things from the 5 volt pin.
thanks
As @Railroader says, you can power the Arduino through the Vin pin or power jack.
Be careful when using the power plug or Vin. Powering through Vin or the power jack means that the Arduino and all peripherals that are on the 5V rail are powered by the weak onboard 5V regulator. The on board 5V regulator is not heat sinked so will supply limited current before it overheats and shuts down. Keep the total power dissipated by the on board regulator to less than 1W to avoid overheating. The amount of current depends on the voltage input to Vin or the power jack. The higher the voltage the less current can by supplied. I would use a buck converter to drop the higher voltage to 5V and connect that to the 5V on the Arduino, bypassing the, weak, 5V regulator if the 5V rail needs to provide much current. Then the rated current of the DC DC converter is available on the 5V line.
With 12V into the Vin or power jack there is less than 100mA for peripherals connected to the 5V regulator.
