I have a problem
I don't understand how to do the simplest thing with it.
I want to know is how to code the NeoPixel after a button has been pushed or sensor
I want to avoid using the delay function
it should work after pressing the button for 5 seconds but run no more than once every 60 seconds
Code: Select all
#include <Adafruit_NeoPixel.h>
int sensor = 2; // PiR sensor
// Pattern types supported:
enum pattern { SCANNER, };
// Patern directions supported:
enum direction { FORWARD, REVERSE };
// NeoPattern Class - derived from the Adafruit_NeoPixel class
class NeoPatterns : public Adafruit_NeoPixel
{
public:
// Member Variables:
pattern ActivePattern; // which pattern is running
direction Direction; // direction to run the pattern
unsigned long Interval; // milliseconds between updates
unsigned long lastUpdate; // last update of position
uint32_t Color1; // What colors are in use
uint16_t TotalSteps; // total number of steps in the pattern
uint16_t Index; // current step within the pattern
void (*OnComplete)(); // Callback on completion of pattern
// Constructor - calls base-class constructor to initialize strip
NeoPatterns(uint16_t pixels, uint8_t pin, uint8_t type, void (*callback)())
:Adafruit_NeoPixel(pixels, pin, type)
{
OnComplete = callback;
}
// Update the pattern
void Update()
{
if((millis() - lastUpdate) > Interval) // time to update
{
lastUpdate = millis();
switch(ActivePattern)
{
case SCANNER:
ScannerUpdate();
break;
}
}
}
// Increment the Index and reset at the end
void Increment()
{
if (Direction == FORWARD)
{
Index++;
if (Index >= TotalSteps)
{
Index = 0;
if (OnComplete != NULL)
{
OnComplete(); // call the comlpetion callback
}
}
}
else // Direction == REVERSE
{
--Index;
if (Index <= 0)
{
Index = TotalSteps-1;
if (OnComplete != NULL)
{
OnComplete(); // call the comlpetion callback
}
}
}
}
// Initialize for a SCANNNER
void Scanner(uint32_t color1, uint8_t interval)
{
ActivePattern = SCANNER;
Interval = interval;
TotalSteps = (numPixels() - 1) * 2;
Color1 = color1;
Index = 0;
}
// Update the Scanner Pattern
void ScannerUpdate()
{
for (int i = 0; i < numPixels(); i++)
{
if (i == Index) // Scan Pixel to the right
{
setPixelColor(i, Color1);
}
else if (i == TotalSteps - Index) // Scan Pixel to the left
{
setPixelColor(i, Color1);
}
else // Fading tail
{
setPixelColor(i, DimColor(getPixelColor(i)));
}
}
show();
Increment();
}
// Calculate 50% dimmed version of a color (used by ScannerUpdate)
uint32_t DimColor(uint32_t color)
{
// Shift R, G and B components one bit to the right
uint32_t dimColor = Color(Red(color) >> 1, Green(color) >> 1, Blue(color) >> 1);
return dimColor;
}
// Returns the Red component of a 32-bit color
uint8_t Red(uint32_t color)
{
return (color >> 16) & 0xFF;
}
// Returns the Green component of a 32-bit color
uint8_t Green(uint32_t color)
{
return (color >> 8) & 0xFF;
}
// Returns the Blue component of a 32-bit color
uint8_t Blue(uint32_t color)
{
return color & 0xFF;
}
};
void StickComplete();
// Define some NeoPatterns for the two rings and the stick
// as well as some completion routines
NeoPatterns Stick(8, 4, NEO_GRB + NEO_KHZ800, &StickComplete);
