The goal of this skills dev was to create an ambient calendar alert, so the neopixel would fade to red 15 mins before a meeting and fade to white when the meeting was over
The process of working with a neopixel was pretty straightforward in terms of the circuit and code. I had the most difficulty making the light fade in and out, and even now I think I could come up with more efficient code in comparison to what I currently have. Additionally working with the IFTTT was initially confusing because I wasn't sure how to initially set it up, but once I got familiar with the website it was easier.
// This #include statement was automatically added by the Particle IDE.
#include <neopixel.h>
#include "neopixel.h"
#define PIXEL_PIN D2
#define PIXEL_COUNT 16
#define PIXEL_TYPE WS2812
Adafruit_NeoPixel strip = Adafruit_NeoPixel(PIXEL_COUNT, PIXEL_PIN, PIXEL_TYPE);
void setup() {
strip.begin();
strip.show(); // Initialize all pixels to 'off'
Particle.function("red", changeRed);
}
int changeRed(String color)
{
uint32_t c;
uint16_t i;
int r;
int g;
int b;
if(color == "red"){
r = 255;
g = 255;
b = 255;
c = strip.Color(r, g, b);
while ( g > 0) {
c = strip.Color(r, g, b);
for(i=0; i< strip.numPixels(); i++) {
strip.setPixelColor(i, c);
strip.show();
}
g = g - 10;
b = b- 10;
delay (100);
}
return -1;
}
else if (color != "red") {
r = 255;
g = 0;
b = 0;
c = strip.Color(r, g, b);
while ( g < 256) {
c = strip.Color(r, g, b);
for(i=0; i< strip.numPixels(); i++) {
strip.setPixelColor(i, c);
strip.show();
}
g = g + 10;
b = b + 10;
delay (100);
}
return -1;
}
else {
return 1;
}
}
void loop() {
}Overall, I thought this was an interesting skills dev cause I was able to connect it to my google calendar making it seem like a useful device. As I mentioned earlier I would want to clean up the code regarding the fading in and out of the neopixel. While the code I have right now does the job, I definitely think there are cleaner and more efficient ways to do so. I would also want to experiment with IFTTT more and see what else I can connect.
