Hello, I have read through all the help topics and seem to still be hitting a brick wall. I have followed the redit post here (
https://amp.reddit.com/r/raspb…tv_guide_ws2812neopixels/) When I power everything on, it flashes the RGB sequence that the Arduino is programmed for. I am waiting for the light strip to then do the rainbow swirl from Hyperion and it just stays off. If I try to search for available servers in the Hyperion app, I find my pi, but nothing changes on the LEDs no matter what I click on the app or inside the Hyperion config java program.. Please can someone help shed some light on what I am doing wrong?
I am using the following hardware
LED WS2812B
Arduino R3
Pi 3 B
Video grabber with UTC007
HDMI Splitter
HDMI2AV
all connections should be 100% correct,
video source > splitter > hdmi2av > video grabber > to raspberry pi.
raspberry pi > Arduino
Arduino pin 5 is to 240ohm resistor then to LED Din and Arduino GND to LED GND
All power run to 5V 10A power supply. Everything appears operational, I just think I'm missing something in the code.
Hyperion.Config.Json is uploaded OpenElec 7.0.1.img to raspberry pi
below is my sketch
#include "FastLED.h"
// How many leds in your strip?
#define NUM_LEDS 240
// For led chips like Neopixels, which have a data line, ground, and power, you just
// need to define DATA_PIN. For led chipsets that are SPI based (four wires - data, clock,
// ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN
#define DATA_PIN 5
//#define CLOCK_PIN 4

Any help would be greatly appreciated. If you need me to run any tests, please let me know what code I need to use to run this. I understand how to use Putty, but I don't know any of the commands by heart.
