Hi all,
so just to get the formalities out of the way, total newb with Arduino so please forgive me if my code isn't in the correctly format or not the "standard" or anything. I am doing a custom lighting sketch for a robot head which consists of 3 NeoPixels. I should add I'm using an Arduino Uno for this.
24 LED RGBW - strip_m
16 LED RGBW - strip_l
7 LED Jewel RGBW - strip_s
Now I have got the Ardafruit_Neopixel library and hopefully I can explain the problem for you:
What I'm Trying To Achieve:
Setup
All 3 NeoPixels to have the same start up sequence using the ColorWipe which has one colour going round the neopixel then is replaced with another colour etc.
Loop
strip_m (24 LED) to have a randomly colour changing effect.
strip_l, strip_s (16 LED & 7 LED Jewel) to have the same pulsing/ fading effect.
Both functions, so all 3 neopixels to be performing their functions at the same time.
What I currently have:
Setup
All 3 NeoPixels run the setup at the same time with the correct colours but the colours do not go round in the ring, all LED's light up, then change to the next color.
Loop
All the neopixels have the correct functions, the strip_s and strip_l both have the correct pulsing/ fading function applied to them and they both run at the same time. The strip_m has the correct colour changing function but the problem is that there is a small delay between them.
The strip_m will change a couple of times but in that time the other two pixels will stop and vice versa.
Hopefully that was laied out simply enough. Below is my code, please remember that it's probably laid our in the wrong format or something but for now it works perfectly fine minus the fact the functions wont perform at the same time.
#include <Adafruit_NeoPixel.h>
#define LED_PIN 9, 6, 5
#define LED_COUNT 9, 16, 24
#define BRIGHTNESS 255, 255, 255
// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip_s = Adafruit_NeoPixel(7, 9, NEO_GRBW + NEO_KHZ800);
Adafruit_NeoPixel strip_l = Adafruit_NeoPixel(16, 6, NEO_GRBW + NEO_KHZ800);
Adafruit_NeoPixel strip_m = Adafruit_NeoPixel(24, 5, NEO_GRBW + NEO_KHZ800);
// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 3 = Pixel type flags, add together as needed:
void setup() { //The start up sequence is a colour wipe of Red, Orange, Yellow, White around all of the neopixels - setup only happens once so all colours go round the pixels once and then into the loop.
/*strip_l = Large Eye
strip_s = Small Eye
strip_m = Main Eye

The code for the pulseWhite function was actually taken from an example library RGBWStrandTest but I removed the parts that made it flash white as I couldn't find anything relating to fading the rings so this was the closest I could get.
Anyone who can help it would be much appreciated.
Thanks
