Hey guys, I’ve been trying to add Bluetooth connectivity to this example sketch but have been unsuccessful. I have a HC-06 BT device ready to connect to my nano. I’m using WS2811 LEDs and just wish to turn them on and off over BT.
If any one can help i would appreciate it.
Thanks

Here is the code I’m running:

/* LedStripRainbow: Example Arduino sketch that shows

• how to make a moving rainbow pattern on an
• Addressable RGB LED Strip from Pololu.
• To use this, you will need to plug an Addressable RGB LED
• you should see a moving rainbow.
*/

#include <PololuLedStrip.h>

// Create an ledStrip object and specify the pin it will use.
PololuLedStrip<6> ledStrip;

// Create a buffer for holding the colors (3 bytes per color).
#define LED_COUNT 30
rgb_color colors[LED_COUNT];

void setup()
{
}

// Converts a color from HSV to RGB.
// h is hue, as a number between 0 and 360.
// s is the saturation, as a number between 0 and 255.
// v is the value, as a number between 0 and 255.
rgb_color hsvToRgb(uint16_t h, uint8_t s, uint8_t v)
{
uint8_t f = (h % 60) * 255 / 60;
uint8_t p = (255 - s) * (uint16_t)v / 255;
uint8_t q = (255 - f * (uint16_t)s / 255) * (uint16_t)v / 255;
uint8_t t = (255 - (255 - f) * (uint16_t)s / 255) * (uint16_t)v / 255;
uint8_t r = 0, g = 0, b = 0;
switch((h / 60) % 6){
case 0: r = v; g = t; b = p; break;
case 1: r = q; g = v; b = p; break;
case 2: r = p; g = v; b = t; break;
case 3: r = p; g = q; b = v; break;
case 4: r = t; g = p; b = v; break;
case 5: r = v; g = p; b = q; break;
}
return rgb_color(r, g, b);
}

void loop()
{
// Update the colors.
uint16_t time = millis() >> 2;
for(uint16_t i = 0; i < LED_COUNT; i++)
{
byte x = (time >> 2) - (i << 3);
colors = hsvToRgb((uint32_t)x * 359 / 256, 255, 255);

• }*
• // Write the colors to the LED strip.*
• ledStrip.write(colors, LED_COUNT);*
• delay(70);*
}

That code does not expect any user input. You have to define what input you want to provide.

That is completely independent from getting the bluetooth hardware connected and working correctly. Do NOT try to get that working in this sketch.
