The Joys of Microcontrollers!

Love Electronics? Then you must love Microcontrollers!

What are they? They are like those little computers (okay, this is not the latest Core i7 that can crunch billions of digits) where there's outputs and inputs, and you can control these ports whenever you wish. Besides that, you can program the chips to give you the desired output.

PIC 18F1320 with music program

In this video, I programmed the chip with the music playing subroutine (the trick is to toggle the pin repeatedly and a square wave output is emitted to the speaker).

By using these things, you can make a programmable-alarm-clock, or a case-mod thing, temperature display system, home alarm system and many more! Besides, almost every electronic thing in your house has at least one microcontroller inside so you might relate them a lot there!

Btw, this chip has a oscillator speed of 4MHz, and it is playing "Minuet in G" from the Anna Magdalena Bach notebook, and attributed to Christian Petzold.

Also, have a Merry Christmas and Happy New Year!

Wow this is hard-core! Thanks for the find!

Well, I must say that I'm still the begineer in those Microcontroller thing. There's still plenty to learn here anyway. I have already completed the basics of PIC 16/18F systems using assembly, and I'm moving to 68HC11 in a few days' time.

Too bad, my 'music box' is only single voice, which is monophonic. I have attempts to make it polyphonic, but I have to use/invent a very complex routine in the Interrupt system, or I'll have to use Real-Time Operating System (RTOS) libraries to make it work.

Also, x86 is totally crazy but it's challenging! Gotta love them sometimes!
