NeoPixels/WS2812B : One wire RGB wonders 

Subscribed-I enjoy the content, delivery, and the fact you respond to comments is a big selling point.

Awesome video with great demonstrations! Those WS2812B thingys really simplify the wiring when project needs multiple RGB leds.

Must be that time of year. My first thought is that those would make for an brilliant Christmas tree illumination.

Great video! I believe they're WS2812B chips, because they look to only have 4 pads on them, instead of 6, but I'd have to go look at the datasheet to be sure. If you're doing a long sting of them, it helps to supply your +5v and Gnd connections further down the line (or again down the line) to ensure the last in the chain is as bright as the first. I've daisy chained about 25 of these to make a 5x5 grid for a project and didn't have any issue with dimming toward the end, but apparently it can happen on longer runs.

Great job! Nice LEDs. Thanks for sharing!

I used Pin 13 for the communication, it is very nice to debug the communication visually.

can you help me, why doesn't this LED light up when I connect it directly to power (3V-5V)? unlike the strip version that I can usually check directly using a 3v battery and lights up, and it happens to all the individual LEDs that I have.

Awesome my friend.

Hi... I would like to know why you have a Capacitor and a Resistor on your breadboard, could you inform me as to the value of both and the reason for these components. Thank you.

Abrupt ending! =( But cool, I've wondered about these.. never really looked them up.. Now I might go buy some =D

Using an attiny85 is fun too, you get a very small form factor combined with an USB charger or battery pack: m.instructables.com/id/Use-a-1-ATTiny-to-drive-addressable-RGB-LEDs/?ALLSTEPS

I had a question about those specific Neopixel LEDs - when they're still attached in a row are they electrically connected as a unit, or are they attached by substrate only and you'd have to solder wires between them to connect them?

I would appreciate it if you did this for ws2813 leds

hey man! nice video! which wire gauge should be used if you want to cut the LED's from a strip and connect them together again? Will 22 AWG suffice? I would like to use 300 LED's in total, so total power consumption is 60mAx300=18W at 5V, so I would at least need a 4A power supply.
