13.OUTPUT DEVICES

Apr 27, 2016

This week's assignments are to add an output device to a microcontroller board you've designed and to program it to do something.

13-1.Board design

First, I designed a board. For this assignment I choose the speaker. And I used this data as reference.
Data > hello.speaker.45.png

13-2.Assemble

13-3.Programming the board to do 'something'

I used following Neil's program.
Data > hello.speaker.45.c / hello.speaker.45.make

And I programed this code by using AVR.
