Solder a piece of 3-ply stranded ribbon cable to the three pads on your NeoPixel strip. (Wires from our premium jumpers work well for this, as do three pieces of silicone coated stranded wire.) |
#include <Adafruit_NeoPixel.h>
const int analogInPin = A9; // Analog input pin that the potentiometer is attached to
Adafruit_NeoPixel strip = Adafruit_NeoPixel(10, 6, NEO_GRB + NEO_KHZ800);
int sensorValue = 0; // value read from the pot
void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
pinMode(9, INPUT_PULLUP);
strip.begin();
strip.show(); // Initialize all pixels to 'off'
}
void loop() {
// read the analog in value:
sensorValue = analogRead(analogInPin);
// print the results to the serial monitor:
Serial.print("sensor = " );
Serial.println(sensorValue);
if (sensorValue < 100){
Serial.println("leds triggered");
colorWipe(strip.Color(255, 0, 0), 25);
colorWipe(strip.Color(0, 0, 0), 25);
}
}
void colorWipe(uint32_t c, uint8_t wait) {
for(uint16_t i=0; i<strip.numPixels(); i++) {
strip.setPixelColor(i, c);
strip.show();
delay(wait);
}
}
