ESP8266 ARDUINO RGB LED STRIP HOW TO

Since current flows in a loop, it doesn't really matter which you have in this case. Either way, the R, G, and B terminals are switched by the controller, and the common terminal is (typically) always connected to the source. These are the RGB LED strips I am looking to use (RGB, no waterproof).įirst, FYI: There are two types of RGB strips: Common anode (ground are tied together) and common cathode (VCC tied together). Would the diagram shown above help in any way, or is it completely the wrong approach for what I'm trying to achieve? If it is kind of the right approach, could I ignore the method of 'injecting' 12v at intervals by supplying a higher voltage 24v at this first 'junction' so that 12v would be supplied to either side, or is that not how it works? If it's not the right solution, would using an RGB amplifier at 5/10m intervals be a better solution? Or, would something like this work:

would this process of 'injecting' at 5m intervals work for a full 30m trip? If so, could I stretch the intervals to 10m for example in order to reduce the amount of wiring round my ceiling?

Is this even the correct approach for what I am trying to achieve? I.e. So, do I only need a 2A supply if I am 'injecting' at 5m intervals? Or would I need a 12A supply (30/5 *2)? Whilst the idea presented in the second figure down makes sense (injecting 12v periodically) makes sense it raised a few questions for me.ĭo I only need to inject just the voltage at these intervals, or do I also need to include the R, G and B lines in the 'blue' wire pictured in the diagram?ĭo the amps matter in this case? Correct me if I am wrong, but a 5m RGB strip will usually run fine off 2A. Whilst researching this question online, I was unable to find any definitive answers for exactly what I needed.

My question is what is the best way of powering a 12v RGB LED strip for 30m whilst keeping just 1 controller as linked above (ESP8266)? However, whilst I do believe this project will work perfectly for an RGB strip up to about 5m, I am aware that lengths larger than 5m require additional consideration when it comes to powering them.įor my project, I wish to make a 30m RGB LED strip to be placed around the perimeter of the ceiling in my living room.

I'm currently interested in following this tutorial which explains how to create a homebridge (ESP8266) controlled 12v RGB strip which is exactly what I've been looking for.
