A very basic example to install and setup LED strip lights. The procedure is applicable to the following models of strip lights - WS2812B, WS2813 and WS2815.
How many LEDs do you want to drive? The solution uses Arduino MCU but the power requirements impose the need for a source that the Arduino alone cannot provide. You can drive a "LEDs" (do a simple sizing calc for Amps based on the number of LEDs) but not the number shown in the video.
I have no experience with LED strips except one cheap strip over my bed wich was pretty much Plug n play but only has 18 LED/m. I want to buy a 5m 60LED/m WS2815 but the vendor says its just the strip. So all i need is a 12v power supply and that wifi controller you got there right?
The power supply, given the many choices, is generally not bundled with the LED strip. Similar observations for the WiFi controller too unless there is a specific bundle being marketed. If you are comfortable with Arduino development you should explore using ESP8266 board with the FastLED library for more customization of the lights than the WiFi controller will do. Also do the basic math on total Amps for the power supply and AWG spec for the wires from the power supply connection to the strip. I've fried, yes fried, a few banana plugs even during short duration nominal testing. Regards.
@@MathaGoram ty....so if i understood correctly: For a 5m Strip with 60 Leds/m and each LED uses 0.3W + 12V P= V*A A= P/V A= (0.3 * 60 * 5)/12 A= 7.5 Do i need more A for the wifi controller?
@@noad9977 The WiFi controller will siphon only mA levels of current. Since its current requirements are two levels of magnitude below that for the strip, there is no need to contend with its demand for the overall current requirements. Your basic calculations are correct. Regards.
The number of pixels is proportional to the power supply for the strip. WS2813 prefers 5V while WS2815 needs 12V. I used 15A power supplies for both but noticed very minor degradation for the 300 pixel WS2813 strip. I did not notice any such effect with a 300 pixel WS2815 strip with the sample code. Of course, the AWG of the power supply wires is very important because a specific AWG is rated for a max A(mperage). There is an industrial grade 20A power supply from the same vendor (but I was not comfortable in using this at home owing to exposed terminals - not a vendor issue). In short, Ohms Law prevails in supporting the maximum number of pixels. Also, I haven't done so myself but others have demonstrated that WS2812B and later (viz. the ones that support individually addressable pixels) permit the insertion of additional power supply connections if one is daisy chaining the strips). Let me do some calculations for you (but please note my initial remarks regarding what worked for me and the standard 300 pixel strips).
Is it possible to do this with an arduino module without purchasing the Sp108?

Hi, which controller are you using in this video? I just purchased WS2815 and I am looking for a good Bluetooth controller to go with it.
Try one of the HiLetgo boards. The tech support is responsive. Rgds.

For a 5m Strip with 60 Leds/m and each LED uses 0.3W + 12V
P= V*A
A= P/V
A= (0.3 * 60 * 5)/12
A= 7.5
Do i need more A for the wifi controller?

@@noad9977 You should leave a little buffer with the amps. What about an 12V 10A power supply which you can find pretty easily on Amazon?
👍👍
Why did you connect the main data wire to CLK and the back up data wire to DAT?
More practical solution to address large number of LEDs individually.
How many pixels will a single controller do?

Basic demo
can i use esp32 for wled for this strip?
Yes of course! Let me know if you run into issues. Thanks.
@@MathaGorami have a problem buddy
How much i want this
You are connected b0 in clk pin?
Я не знаком с b0 для Arduino/ESP8266; используя только D2/GPIO4.
Volt? Amper?
5 V DC; > 15 A (sic) for the example.
