Help Choosing Appropriate Adapter

Post by Boans »

Hello all, I am really new to this and have a project where I am going to run 2 1-meter strips off of an Arduino.

I will be using 2 one meter strips from this reel:
https://www.adafruit.com/product/1376?length=5

My question is, is there an adapter that I can run both off of? Ideally, I'd like to have one adapter powering my enclosure which would contain my Arduino and 2 strips.

The problem is I believe the Arduino calls for a 7-12V supply and the strip calls for 5V.

Can anyone recommend an adapter that could power both and maybe any tips on how to split the power properly - or does anyone know of any videos that feature a similar project?

Thanks so much for any advice.

Sounds like an Arduino UNO?? Assuming that...

The UNO is a 5v board. The higher voltage supplied to the barrel connectors immediately gets converted to 5v. You can power the UNO with 5v via the USB connector, though.

You'll need a 5v power source for the strips that can supply ~2A per meter. So that's 4A. This would do the job: https://www.adafruit.com/product/1466 and could power the UNO through the USB connector as well since it would need much.

Thanks a bunch Dave. Yea, I forgot to mention it was an UNO. I won't have the option of powering the Arduino separately through USB so do you think I could power the whole setup from something like one 5V (6A) adapter and somehow split the power between the two?

Or I just realized you might be saying it could power both .. by using some type of splitter to USB? Sorry I just didn't understand exactly what you meant.

Yes, that's what I mentioned. You can give the UNO 5v through the USB connector. That 5v can come from the power supply, it doesn't have to be from a computer. You could wire one of these https://www.adafruit.com/product/3629 to your 5v supply and use a USB cable to power the UNO.
