    thanks for making this channel your videos are great! I understood binary represented 16 possible states of 4 binary numbers, but i never realized they were numbered 1, 2, 4, 8 & that's why you're able to get specific numbers XD
    very simple & informative

    You are an amazing teacher. This is mind-blowingly illuminative, and everyone interested in electronics should watch and follow this video at least once.

    Not certain about the points made but ,if anyone else trying to find out introduction to electronics courses try Ichordo Electronics Expert Fixer (just google it ) ? Ive heard some unbelievable things about it and my co-worker got excellent success with it.

    People still use WordPad? I use Notepad++, but I only see people using Notepad, not Wordpad. Great video though. I'm a CS student, so I know about binary. I was just watching this for the electronics part.

    The decimal equivalent of 64 bits is:  18,446,744,073,709,551,615.  To  calculate it you could use the formula for a partial sum of a geometric sequence as I described on my previous comment

    The decimal number que representa the 64 bits is calculated with the formula for partial sum  :  sn = a1(1-r^n) / 1-r       ….>>>>s64=1(1-2^64)/1-2  > s64=1-2^64 / -1

    Excellent explanation about the binary numbers, that's the way it should be explained in high school.  I didn't have a cleared understanding of how actually the binary numbers work.    I understood that the 8 leds when all on it represent the decimal number 255.
