Hi, I would like to connect 2 led strips to Arduino in order to control them.
I don't know if Arduino should have enough power for that and in case it would not, what should be the best path to go in order to give them enough power?
Both of strips would be around 60 cm length and they would be connected to Arduino with additional cable (since I don't really need more strips than I told) with length around 53 cm each.
Besides power problem, what would be the best cables to connect Arduino with led strips?
An Arduino is a controller, not a power supply.
So you should never power anything significant from it.
You might be able to power the Arduino from the LED strip supply,
but you didn't tell us which LED strip you're going to use.
There are dozens of types, all with different power and drive requirements.
Leo..
DO1, DO2 and DO3 are digital outputs. The arduino as mentioned is not a power supply. The illustration uses an external 12 volt power supply and the LEDs are Common Anode. You really need to provide much more information on your project to get any useful information.
Sorry, my bad for missing out that info. I have Commel 405-203 (SMD 5050, 12V) led strip.
Here are the details about the project:
I tend to make audio visualizer out of my desk. From each side of the desk will be a led strip inside aluminum channel (I don't know other English word for that) which will visualize what microphone picks up. I have done similar project but with led matrix panel (4x5), so I tend to pick up what have I done with that project and reuse in new project. Here is the link to previous project GitHub - Ryukote/Visuino: Audio visualizer using Arduino Uno R3 (code is ugly I know, I am not C developer, but it works).
I will place Arduino from bellow the desk and microphone in the desk hole I made for cables.
The goal is for microphone to pick the music I am listening so Arduino can visualize that music on led strips (both strips at the same time with same visualization).
Ron's circuit should work as long as your LEDs are common anode (common positive). I didn't find the detailed specs.
The specs do say 14.4W per meter so that's 1.2 Amps per meter (14.4W / 12V). Your power supply has to be capable of at least that current and each MOSFET has to handle 1/3 of the total current.
Having LED respond to audio is most commonly called a "Color Organ" circuit. Can be done with discrete components or with a uC like an Arduino. This is a project using an Arduino which may need tweaked for your application but has the general idea.
