Mengendalikan Motor DC dengan Remote Kontrol IR Menggunakan Arduino dan L293D

/*
 * Original Infrared library from - http://arcfn.com
 * 
 * This is Arduino code for the L293D DC motor driver.
 * It uses an IR remote control to rotate the DC motor clockwise (CW), counter-clockwise (CCW), and stop it.
 * Watch instructions for this video: https://youtu.be/e0pvfJbdw_o
