we are still having trouble with our LED strip. We fixed the library issue, and are now trying to program the LED's but have run into a few issues. 1) First of all, our LED strip does not consistently light up. We are using a 12v battery and everything is wired correctly, but how the LED's appear is very inconsistent. Not all of them light up, they are all different colors, and are all of varying brightness. We have tried to resolve this by just powering it with the battery, using our arduino as a power supply, and added a 1000uf capacitor to make sure the strip doesnt get a surge of power and short the strip. Our code is this:
/* Arduino Tutorial - How to use an RGB LED Strip
Dev: Michalis Vasilakis // Date 3/6/2016 // Ver 1.0
Info: www.ardumotive.com */
//Library
#include <Adafruit_NeoPixel.h>
//Constants
const int dinPin = 4; // Din pin to Arduino pin 4
const int numOfLeds = 10; // Number of leds
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(numOfLeds, dinPin, NEO_GRB + NEO_KHZ800);
// Color takes RGB values, from 0,0,0 up to 255,255,255
// e.g. White = (255,255,255), Red = (255,0,0);
int red = 255; //Value from 0(led-off) to 255().
int green = 0;
int blue = 0;
void setup() {
pixels.begin(); // Initializes the NeoPixel library
pixels.setBrightness(100); // Value from 0 to 100%
}
void loop() {
// For a set of NeoPixels the first NeoPixel is 0, second is 1, all the way up to the count of pixels minus one.
for(int i=0;i<numOfLeds;i++){
pixels.setPixelColor(i, pixels.Color(red,green,blue));
pixels.show(); // This sends the updated pixel color to the hardware.
delay(10); // Delay for a period of time to change the next led
}
}
We are trying to set all the LED's to red just to test the code, but nothing is working. Has anyone experienced this before or has any idea of what is not working?
