TATTOO
Cartel de TATTOO
Que mejor para un tatuador que tener su propio cartel llamativo.
Materiales usados:
x1 Arduino Nano
x1 alimentador de 5V 2A
x1 tira de neopixel cortadas a medida. (WS2812)
x2 circulos de neopixel de 24 leds (CJMCU-2812B-24)
Cada letra se formo con tiras de leds neopixeles a medida.
T = 5 led + 5 led
A = 6 led + 6 led
O = 24 led (1 circulo)
Arduino Nano se uso los pines de alimentación(5V y GND) y para la salida de datos el PIN 2.
En el pin 2 se puso una resistencia de 470 ohms.
Todas las tiras se pusieron en serie a través de los pines de entrada y salida( DIN o DOUT )
Para hacer las uniones con los cables y que no se viese nada, se hizo un corte con el cutter justo donde termina la tira.
Se mete el cable por detrás y solamente se suelda la punta del cable.
Se estira un poco para ocultar el cable y que no se vea nada.
Después de las soldaduras se hizo el marco reutilizando un marco de una Tv. Así como los papeles reflectante de la luz, que llevan las pantallas de Tv internamente.
Código:

#define PIN 2
// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(98, PIN, NEO_GRB + NEO_KHZ800);
