Thanks. And I'm thinking that example sketch may be a little too fancy for troubleshooting, now that I look at it again. Let's switch to something super simple. Something that just lights up basic colors and nothing else:
Code: Select all
Adafruit_NeoPixel.h>
#define LED_PIN 17
#define LED_COUNT 15
Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);
void setup() {
strip.begin();
strip.setBrightness(50);
strip.fill(0xFF0000);
strip.show();
}
void loop() {
}
With that, should get solid red on all pixels. Or, can change the 0xFF0000 to some other color and try that as well.
