Control LED with more than 1 digital Pin Neopixel

Other Hardware LEDs and Multiplexing

Hi guhs i have a led strip with code WS2811 12V 3 Led per IC. So I have a length for 1.8m LED STRIP with 3 lines and those strip made with parallel and connected with the same led stripset so I have 2 set connected. The problem is the Voltage and Ampere doesn't support the LED enough so I have a plan to give each lines 1 digital pin output to get enough power. Does anyone know how to apply more than 1 digital pin output to the LED. Here's my before neopixel function, but the function can only put 1 digital output

Adafruit_NeoPixel strip = Adafruit_NeoPixel (Number_led,number_pin,NEO_GRB + NEO_KHZ800);

ahh i get the answer done, Adafruit_NeoPixel CHANGE THIS = Adafruit_NeoPixel (Number_led,number_pin,NEO_GRB + NEO_KHZ800);

Sorry, but that makes no sense whatsoever! :astonished:

so I have a plan to give each lines 1 digital pin output to get enough power.

Are you new to electronics? The plan is a nonsense. It will affect nothing.

Once the signal going to the LED strip reaches the first set of LEDs it gets regenerated and starts off fresh to the next WS2811 that controls the next set of three LEDs. This has nothing to do with the current needed to drive the whole strip, which normally needs another external power supply to drive it.

The number of LEDs you send to the Adafruit library should be one third of the number you actually have on your strip.

yeah i know it regenerate when going to another ic, but if you light it up all with color white which takes a lot of power will effect the last column of the led

so thats why i need more power at the last led, its about 2m length. It's not about the number pin the led is turn random but I solved it now

It is the case that you always need a power cable rated for at least half of the full current you expect the strip to draw - can't figure it for your strip as you have not specified how many LEDs - running in parallel to the strip and connecting power (12 V and ground) in every 60 LED groups or so and at least at each end.
