Hi Julian, Enjoyed this very much.
great video! the best one explaining APA102! keep the great work!
I don't believe that any LED strip acts like a shift register.
The video leaves only a (small) part of the code, can you put the complete code for the Arduino here ? Thanks in advance.
I have made the switch from ws2812 to APA102 and am dealing hoping to expand much the arduino code I have been using to accommodate the additional clock pin. Any suggestions?
Hey, i have a 4 line strip too, but it has 12v, g, r and b. can io set different colors on these too?
i used wsb128b. but after some times they dont work anymore i dont know why some say you should try capasitor or bustermination but that dont work is apa101 more stable ?
how did you make the coin buttons? awesome!
This is an excellent demo. You will still get dozens of middle Eastern dudes asking for your source code and wiring so they don't have to really do any work. rats.
пиздец убогийнах
Can this run at frequency of something like 150MHz?
Nice LEDs, but I prefer the other addressable LEDs you showed before, they are very simple with just power, ground, and a single data line.
WS2811 14 X 9 MM. PCB: Can I use green single color against the green side and yellow single color against the green side red against green entrance no RGB LED I mean single colors. Does it work if you set the right color?
One of the most helpful videos on the entire internet! 10 out of 10!
I seems to always get confused with bits and bytes. if there a way to send bits with an arduino or is it easier just to use bytes? I always thought a bits were either a 1 or 0. and bytes were "packets" of ones and zeros.
You briefly talked about the power supply. Is that a 2 amp supply? I was wondering if you could help with how to power these things and how to figure out what kind of power you need for x number of pixels. I just got a meter at 144/meter.
Also I noticed that you don't try to power it directly from arduino which makes sense. I cut open the other end with the power and the black/red power cables are soldered to the same black red that attaches to the arduino. i see that you didn't attach the red (+) line to the arduino. But can I power my arduino (nano) and the led strip from the same power supply? Ultimately I'm using these for things like under counter lighting and interesting wall lighting. I need a solution where I can have a single power supply driving the arduino and the leds.
Any helps or further hints appreciated. Love this and the #2 video. Really took the mystery out of these pixels and how to program for them. Thanks!
