ok so i have a WS2812B and a nodemcu. I need to power about 10 ft of the led strip and want to have wifi.
Im a complete noob with this stuff so i need some help. After programming the nodemcu can i just wire the led strips to the nodemcu and use it like that? or do i need other components?
this is the link to me led strip
this is the link to my nodemcu
Is this of any help?
Or this?
I have not used either of these components but from looking at the specs, the data inputs look compatible with standard Arduino , TTL 5V logic levels. You will need an external 5V supply capable of supplying 2A for each 30 LEDS.
At 30 LEDs / metre, 10 metres will be 300 LEDs taking 20A, a reasonably big powersupply.
Though as I say, I am just looking at the specs so I may not have it all correct.

yea it helps a little but they are using a relay, i saw one made without a relay and was wondering how its done. Or maybe i was mistaken

Its only 3m wanted though (10 feet), and its 1.8A per m, so about 5.5A, not 20A.

Silly me. Makes it a lot easier.
