آموزش راه‌اندازی ماژول PWM TLC5947 با آردوینو (درایور LED 12 بیتی)

/*************************************************** 
 * TLC5947 TEST base on adafruit library example 
 * electropeak
 * ALi Akbar Hosseini 
 These drivers uses SPI to communicate, 3 pins are required to 
 interface: Data, Clock and Latch. The boards are chainable

 Fixed typo in all occurences of NUM_TLC5947 (was 5974)
