Hello;
i want to create a static color show for my ws2812b led strip, lets suppose i want only to show red color behind my tv, so how to make sketch? please someone write and share.
thanks
Hi AskFriends,
(see also the Arduino LED effect article)
When using the FastLED library, you could do something like this:
#include "FastLED.h"
#define NUM_LEDS 60 // Number of LEDs in your ELD strip
CRGB leds[NUM_LEDS];
#define PIN 6 // Arduino pin used for LED strip
void setup()
{
FastLED.addLeds<WS2811, PIN, GRB>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
}
void loop() {
for(int i = 0; i < NUM_LEDS; i++ ) {
leds[Pixel].r = 0x00; // Red
leds[Pixel].g = 0x00; // Green
leds[Pixel].b = 0xFF; // Blue
}
FastLED.show();
}
For AdaFruit NeoPixel library something like this:
#include
#define PIN 6 // Arduino PIN
#define NUM_LEDS 60 // Number of LEDs in strip
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);
void setup() {
strip.begin();
strip.show(); // Initialize all pixels to 'off'
}
void loop() {
for(int i = 0; i < NUM_LEDS; i++ ) {
strip.setPixelColor(Pixel, strip.Color(0, 0, 0xff));
}
strip.show();
}
(Note: updated code, replace red, green and blue with numbers)
Hope this helps 
THANK YOU SO MUCH.
No problem - hope it was you were looking for
