LANGKAH PERTAMA :
LIBRARIES
KEMUDIAN :
KETIKKAN NEOPIXEL DAN PILIH ADAFRUIT NEOPIXEL
COBA DULU EXAMPLE NEOPIXEL :
begitu pula silahkan cari example yg lain dan dicoba
DIBAWAH INI BERVARIASI : UNTUK MENGUBAH VARIASI LAIN SILAHKAN INTERUPP ATAU TEKAN BUTTON DI PIN 2 YAA..
ATAU CUKUP DISENTUH PIN 2 ARDUINO.
KODING :
