Calculate LED Strip Voltage Drop With 💡QuinLED💡: You'll Be Surprised How Many Wires You Need!

Power injection can be the most frustrating thing about addressable LEDs, especially with 5v. This video guide will perfectly explain to you why this is happening and how to calculate everything for *your* setup so that you know it'll run perfectly and without limits!

This is the best video you have made for beginners. I was really overwhelmed when I got my Dig Quad but now I feel a lot more confident.

[simonvann]

Fantastic explanations, really helpful for people like me who are just getting in to LED controlling. Thank you, keep the videos coming.

[centralseac]

What a complete, super detailed explanation of just about everything needed to get up and going. Thank you so much, extremely helpful. Have a great day.

I lost track of how many "ohhhh that's how that works"/"ah ha!" moments I experienced watching this lol

[umamichefd]

Now I understand, I've been watching your videos(quite a few of them) putting light strips in my aliexpress cart, kinda planning out what I need to buy. But I wasn't really sure how to wire it up and everything.

I ordered the little solder gun/ heat gun kit you posted. Ordered some other tools, pigtail connectors, etc.

But THIS video tied it all together. I'm now confident in taking on a few projects I've been planning out in my head. I'm now able to put them down on paper, fully drawn out, knowing exactly where, how and WHY I need to run the wires.

Huge thanks for taking time to make these videos, i can't wait to get started.

[alinconstantingoga]

one of the best tutorials i have ever saw for adressable LED's . Thanks !

[jeffro.]

I'm SO GLAD that you're covering wire guage (diameter)! Seems that so many people just don't get that!
Also i like the fact that you even mentioned using fuses! I've seen so many comments where ppl just burn their chips up, because they only rely on powering from one point. Like on Amazon, these dimwits complain that the 2d arrays are "obvious low quality" because they get hot quickly and then burn up the whole matrix.
They're unable to utilize their brain to figure out something simple like injecting amps elsewhere.
Hopefully, you've given some ppl something to actually think about.
But, i doubt those types would sit through all the talking, anyway.
Oh, well.
Great video, anyway!

70 minute video, lifetime of problem solving in LED installations :D

[auser]

This is such a great video — thank you! You make it clear and easy to understand. Just finished sizing out my power supply needs for my LED layout after watching this video.

[samgendler]

This was an incredibly useful video. I have a much better understanding of how to select parts for my builds now, and I'll definitely hop on the discord prior to embarking on any really significant projects.

[kajuta]

YES YES YYEEEESSSS! This filled in so many questions I was trying to research (Im new to all this just a few days now).
I watched this now several times today, replaying many sections till it sunk in.
I'll share my initial design with the discord to have someone double check my math.


Thanks again!

[big-ted-]

Long overdue to have information on how to calculate and inject power the correct way

[williamkent]

Wowww this was amazing. So well done. Its amazing how hard it is to find all this info online. Thank you! Planning to join the discord, and ask for advice on my planned setup.

[Random-rtec]

Purchased the DigiQuad for my 1st ever WLED home project and so far I am very happy. The Quad was surprisingly easy to setup and so far I have used it to test each 15 foot section of 5volt 60leds/meter as I complete them. When done I’ll have 4 channels of sound reactive fun in the basement playroom.

[homeflavor]

I just learned EXACTLY what I was looking for. thank you, this was a GEM of an educational resource

[TheBEGamer]

This hour long video helped me out A LOT!!! So thank you for that.
I just have a question about the long Data+GND wire. What AWG wire would you use in your scenario @49:00 for that Data+GND?

[pjotr]

The missing link has been released: A decent video to refer to when people start to use led strips. Thanks!

[gameamder]

What can i say...

Thx for all your time, and Big THANK YOU for helping me finally understand everything about led strips...❤

[leinitta]

This guy is the best…hope he makes a dig uno mini one day so we can run 24v cob leds & replace all the govee projects & put the dig uno mini in the cutout area where the govee controllers are.

[Zinic_]

I have a question about running a data wire with ground next to it (1:08:57). Should the ground be connected to the LED strip or can the ground wire not be connected to anything?
