Hi all,
I’m working on a basic Arduino project to control some LEDs for ambient lighting.
Arduino Uno / Nano
LED strip or high-power LEDs
On for long periods
What’s the recommended approach here?
PWM + MOSFET, or addressable LEDs?
Any key tips for power supply and wiring to avoid issues?
Thanks in advance for any guidance.
Try looking at this
Are you using LED strips, or addressable RGB leds ?
The control and power strategies are quite different.
Best to post links to the parts you’re planning to use ?
Just white or colors?
12V and 24V strips use less current than the 5V strips, so you can use thinner wires,
addressable RGB
It also comes with a controller, power supply, and switch.
If you already purchased the strips, with a power supply and controller, why are you asking about the recommended approach?
Probably the next step you need to take is reading the data sheets and planning your power supply.
Long strips may need power injected at multiple points to share the current distribution.
Shorter strips can be fed with power from one end.
Addressable LED strips use a multiplexed serial data stream to control the brightness and colour - that also is fed in at one end.
I'd like to know how to wire the wires more properly.
Just follow the instructions for the strip, power supply and controller that you have already purchased. You don't need and Arduino since you already have a controller.
I imagine you just simply plug the components together.
Do you have a link to the website where you purchased the strip?
I don't think it's that simple, because an extra switch has been added. And there are two different types of LED strips that require one power source.and they need to be connected in parallel.
See Post #2.
Show it.
Why? See Post #2.
Addressable RGBLEDs are exactly that.. you tell the LEDs which one(s) to light and which color... while connected in series.
Those are not addressable RGBLED. Your link in Post #11 goes to a page of 100 different LEDs.
Post useful information about your LEDs. Find its "datasheet."
[edit]
I see the RGB... still need the datasheet.
Who added this switch?
And there are two different types of LED strips that require one power source.and they need to be connected in parallel.
What are you connecting them to?
What is this power source?
What controller do you have?
