Adafruit LED Sequins - Ruby Red - Pack of 5
All prices are VAT included
Sew a little sparkle into your wearable project with an Adafruit LED Sequin. These are the kid-sister to our popular Flora NeoPixel , they only show a single color and they don't have digital control, but that makes them smaller easier to use for many projects.
Simply connect 3 to 6VDC to the + pin and ground to the - pin, and the LED on the board will light up. You can make the LEDs fade and twinkle by using the PWM (aka analogWrite) functionality of your Gemma or Flora , or just connect directly to a digital I/O pin of a microcontroller to turn on and off. Or even skip the micro altogether, and power directly from a LiPoly or coin battery.
This order comes with 5 Ruby Red "1206 size" LEDs, matched with a 220 ohm resistor. When powered from 3.3V they draw about 5mA so you can put up to 4 or 5 in parallel on a single microcontroller pin. We also have these sequins in warm white , emerald green , royal blue , and rose pink .
