00027 *    @description of the program: 
00028 *
00029 *    Brushless motor control program with L293D. 
00030 *    L293D is a simple, cheap standard DC motor driver and can be found easily.
00031 *    But I should say that controlling brushless motors with L293D is not efficient 
00032 *    and precise. Proper way to control brushless motor is using an ESC or drivers
00033 *    like L6235. For the time being I have none of them, but I had a brushless motor that 
00034 *    I wanted to control and see how it works. If you want to do the same, that program
00035 *    is for you. 
00036 *      
00037 *    This guy did a great job by explaining how it is done:
