LED Power Question and Parts

1. offizieller Beitrag

    Hi Everyone, I've been doing a lot of research and I've just got a couple questions about my setup before buying the parts.
    Just wanted to double check if I need to wire every Grd/5V separately on each of the 4 strips (similar to this post)
    Or would I have enough power to power the all the LED lights by just connecting the ground/5V from the end and beginning of the strips. Also wanted to know if I need to change up my parts list or if I'm missing anything. Thanks so much!


    LED information
    106cm x 63cm (Total LED's required) = 3.38m
    203 LEDs x 0.06A = 12.2A required

    Hi,


    If i can help you with your config. A friend of mind find a new product, the Hdmi VideGrabber. I test it and it's working great.



    You can find it here https://fr.aliexpress.com/item…=a2g0s.9042311.0.0.5GtcYz


    I don't know if you can find it on Amazon. Note that the LEDs is not a real APA102 but an APA102C and sometimes a SK9822. The real APA102 look like that



    The price is not the same, 20$ /meter.


    Thank you for your list, i saw that an adapter like that wasn't limited to 10A. I recommend the use of L Shape corner for the angle :

    But sometime it's hard to find a 12mm 4PIN RGB.


    And for more efficiency you can powered your LEDStrip at the begining and at the end with an Y cable DC 5.5/2.1.


    The rest of your list is good i guess. If you ask who i'am and why i answered you can check my blog https://translate.google.fr/translate?hl=fr&sl=fr&tl=en&u=https://ambimod.jimdo.com/


    Note for @Administrators... I can translate some of my tutorials or vital information if you want because for exemple i saw that some information are missing like the possibility to use 2 LEDStrip maybe 3 on the same Raspberry or the good LEDs/Choice or All Ambilight possibility, the multizones effects....


    For Info i used a WS2812B and a WS2813, one with the SPI mode and the other with the PWM mode.

    Sorry Jon i pollute your post lol.

    Hi,

    Sorry Jon i pollute your post lol.


    Hi! Thank you so much for your response. Sorry I had bought some parts already before I saw your post :( So I got the APA102C LED. I hope this will not be a problem.
    I also was wondering is the L Shape connector you are talking about?


    can you tell me the difference between SPI and WPM PWM Mode in your example? I was wondering which mode I need for the APA102C. Also I read up about maybe I need to get a level shifter? Do you think I need this? I'm very new and I'm not sure how to use this level shifter. Do I need arduino? Your post says Optional Arduino or NodeMCU microcontroller for connecting LEDs. What is this one for? Sorry for so many questions


    Please don't say sorry because your post is very helpful. Thank you

    Jon my friend,


    I'm really happy that you ask me all this questions lol, and i'll answering you with pleasure.


    I will give you a quick tutorial to make you understand some Ambilight installation.


    You need to know that two kind of LEDs exists :
    - The PWM with a 5V, GND and DATA wires
    - The SPI with the same wires above + a CLOCK


    So normally the PWM have 3 Wires and a SPI 4. An exeption was the WS2813, SK6822 and CS2803 with 2 DATA for Dual signal when a LED breaks down.


    You can use many profile on hyperion according to the LEDs technology choosen and the way we connect the LEDs. Before the work of @penfold42 we need to use an Arduino with PWM LEDs but now we can plug directly the LEDs on the Raspberry.


    We can choose two Mode, the PWM and the SPI. For PWM, 3 GPIO are available on the Raspberry but as the wiki said, it cause a problem with analog audio use so he create the SPI mode for PWM. ( DATA on GPIO10, the same GPIO used by real SPI LEDstip ).


    Now we will see the way you can plug your LEDstip :


    - The first way is to plug the LEDs directly on your Pi. With the works of developpers we can use PWM or SPI LEDstrip directly with a Raspberry. ( and plug more than 1 for the PWM. Good thing for a local MultiZones for exemple )
    - The second way is to use an Arduino connected on Raspberry USB using Adalight profile.
    -The Third way is to use an Arduino Wifi Capable, an NodeMCU/ESP-01/ESP8266/ESP32....and have a Wifi Ambilight.


    So we can ask this question : "Why use an Arduino or NodeMCU when i can plug my wires directly on the Raspberry ?"


    If you can do your installation without this objects do it but sometimes is preferable to pass by one of this ( NodeMCU preferably ).


    NodeMCU are very convenient because you can have an Ambilight Over the Air. With a NodeMCU you have many choice like :
    - Do a wireless installation with a UDP communication between the Raspberry and the NodeMCU for the LEDs present on the back of your TV
    - Do a Multi-Zones installation. You can have 4 more LEDstrips with 4 NodeMCU ( represent the side of your TV ) on your room. For exemple you can put the Left/Right LEDstrips on the Left/Right wall, the Botton on the floor and the Top on the ceiling creating a sort of Lights propagation thru the wall. Is hard to explain but a video is better than word.
    - Create Hue Like bulb

    I don't want to be boring so i'll stop here with information without interest for you. The most important is "Which installation i want really want to have ?" A Wired or Wireless ? "Which option ?" Hue, Orb, Yeelight, MultiZones...


    After you answered these questions the rest will come naturally . To finish i never use a LevelShifter with all and different installation i made but it's very simple to use and i don't think you need this. I can give you an installation picture if you want.


    Voila, if you have more question i'll give you more answers with pleasure.


    YouS

    Hello, Thank you very much for the detailed explanation! I think because this is my first project I want to make sure I try to keep it simple. I think I will just use my APA102C to directly plug it into the Raspberry Pi in order to avoid complexity. Maybe in the future I will use NodeMCU because the video you showed me looks very cool to use Over the Air technology. I think in my case I will start with SPI Mode. Can you please double check before I buy is this L Shape Connector one that works with my APA102C Lighting? It seems to have 4PIN but I'm not sure is it 12mm RGB.



    Thanks and I'm excited to build this new project

    Sorry i forgot the L Shape with my long explanation. :omg:


    I saw that it's not the good size, only 10mm and not 12mm. Try this one https://www.ebay.com/itm/20PCS…40ca9e:g:Y2IAAOxyWalR5XfI
    But you need the small PCB not provided https://fr.aliexpress.com/item…5pcs-lot/32811243536.html


    It's better if you find the both together. Try bangood maybe.


    Glad to help you in your project ;)

    Yes i know but i don't find yet a reseller with 12mm pcb. Maybe do like you said will be a solution ( difficult for me to write in English lol ).


    A few months ago i found reseller with full L Shape Corner but he is out of stock permanantly https://fr.aliexpress.com/item…D-strip/32396338202.html?


    I ordered many 12mm pieces on aliexpress but i always receive 10mm :(


    If i found what you're looking for i'll inform you ASAP.


    Wait, i'll give you some possibility.

    Thank you! :)


    You're welcome. I made a mistake for the last one lol. It's in stock but will arrive in France after Christmas, i need some rest lol. And it's the not a good one :facepalm:.


    I'm going to bed :unsure:. As i told you it's very difficult to find a 4Pin 12mm L shape in all country :eek:

    Jon, it doesn't give very clear idea fromfyour photo but diddyou double check connections between cables and the card? For example Ono your photo, I couldn't make sure where the black wire comingcout of led is going? Etc.. Etc...

    Hi I've double checked the connections and all the lights do light up when I remove the GND wire from the PI but for some reason when I'm sending the signals from the PI it doesn't seem to work. I am also using a level shifter. Can you please take a look at this picture to see if my wiring is okay?
