I recommend a "composition" or spiral notebook, not a looseleaf notebook, for your "permanent" (i.e., re-written) notes. Then, as soon as possible after class (preferably that evening or the next copy your notes into your permanent notebook. The main idea behind re-writing your "raw" class notes (besides making them more legible and organized) is that the very act of copying them is one of the best ways of studying them! Further study of your class notes can then be done from these "cooked" ones that are neater, more legible, more organized, and more complete. I will suggest ways to do this later. Use this opportunity to fill in gaps from your memory while they are still fresh in mind.

Notice that this amendments section is titled "take notes in Class rewrite, them at, home the title was not "take notes in Class study, them at Home". Of course you should study your class notes at home; but just (re-) reading them is too passive. One of the themes of this guide is that studying must be active. It is all too easy when just reading passively to have your mind wander or even to fall asleep: Moreover, notes are often incomplete or sketchy; just reading such notes won't help. And a few days or months after you take them, they may very well be illegible or incomprehensible. Finally, if you don't do something active with your notes, you run the risks of having unorganized notes or of misplacing them. What I suggest is that you study your notes by re-writing them. For each class, buy a separate notebook from essay the one you take your notes.

It can be a timesaver to take an hour and causing error deliberately, report so you know what the error messages are caused by for later reference. Sharing your library with other people One of the fastest ways to flush out bugs in a library is to let other people use the library. Often people not only find bugs but also contribute patches to fix those bugs. (1) Post your library online somewhere, perhaps one of here in the Arduino Playground the launchpad source code hosting using the bazaar version control system.

H you will get a series of errors if you've forgot to include the Arduino, and trying to use some of the Arduino functions or datatypes. It is only necessary to include the Arduino. H in empire you library. Cpp will include it because it includes your header. Delete object file and recompile between each alteration of header and/or source When changes are made in the header or the source, those changes are not automatically incorporated in the object file of you library. To be sure that your changes are compiled and used, delete the led13.o and recompile a sketch in the Arduino ide. Note: After making library changes, before recompiling, you may need to delete the libName.

'myDescriptivevariable' writing examples be sure to create examples that are as self describing as possible. Additionally it should be made an effort to demo most of the functions. Blink Example include led13.h led13 led initialize an instance of the class void setup nothing to setup void loop led. Blink(2000 stay one second on, then a second off get Code keywords. Txt Remember to implement this file, as it makes using your library a lot easier. Our library has four names that needs highlighting. Those are: led13 on off blink And they are implemented in keywords. Txt as: led13 keyword1 on keyword2 off keyword2 blink keyword2 Debugging Remember include arduino.

Line 13 is the end of the class. Line 15 ends the ifndef preprocessor directive led13 source you will see that this source will be very much like the concept sketch. However, i've changed some datatypes, and the rest is just the c syntax. Notice the :, it is called the 'scope resolution operator' include "LED13.h" /include the declaration for this class const byte led_pin 13; /use the led @ Arduino essay pin 13, this should not change so make it const (constant) / constructor setup the led, make pin.

For Arduino that will often result in all variables declared private, and most functions defined public. Selecting datatypes / returntypes being the Arduino has limited resources I think selecting the 'smallest' variable is the way. An Arduino pin will (probably) never become above 255. So in that case using a byte is sufficient, and preferable. Selecting variable- / functionnames The arduino api has established some cues for how to name a variable or function. Start lower case, and indicate new words with an easy upper case letter.

You probably know how to write functions that has parameters, but here it is: /make the led blink void blink(int time) on / sets the led on delay(time/2 / waits for a second off / sets the led off delay(time/2 / waits for a second. Complete concept sketch int ledPin 13; / led connected to digital pin 13 void setup / run once, when the sketch starts pinMode(ledPin, output      / sets the digital pin as output void loop / run over and over again blink(2000  /call the code. The declaration, referred to as the header file. 'led13.h' will indicate that the file declared the class led13. Declaration is the process of defining what the class should. The implementation, referred to as the source file.


'led13.cpp' indicates that the file implement the declared functions and variables from "LED13.h". Implementation is the process of writing the code, that determines how the declared functions are imlemented. Led13 header ifndef led13_H define led13_H include arduino. H class led13 public: led13 led13 void on void off void blink(int time ; endif Get Code 'code Analysis: ' lines 1 and 2 are referred to as an include guard It basically prevents the code from being included into the program binary multiple times. Line 4 includes the Arduino code to our library. This enables us to use the pinMode, digitalWrite, delay etc. Line 6 is the beginning of the class itself. Line 7 uses the public keyword Line 8 and 9 are called constructor and destructor, they are responsible for setting up your library (construct and delete it (deconstruct) Line 10 declares the function 'void on, this will turn the led on Line 11 declares the.

I suspect this is not surprising, being that we know this code will blink the led connected to pin. Now, write blink inside the loop, so that the code that once was inside the loop and now is located inside blink, gets executed (because loop calls blink). Now, you should have a sketch looking like this: int ledPin 13; / led connected to digital pin 13 void setup / run once, when the sketch starts pinMode(ledPin, output / sets the digital pin as output void loop / run over and. These will be really simple functions, because they will actually just 'wrap' digitalWrite(13,high) and digitalWrite(13,low) respectively. Go ahead and try to write these functions. You should end up with something like: /turn the led on void on digitalWrite(ledPin, high /set writing the pin high and thus turn led on /turn the led off void off digitalWrite(ledPin, low /set the pin low and thus turn led off get Code we have. As ions the code is now, the blink will always use two seconds, but we wanted to pass the number of microseconds as an argument. Additionally we'll want to remove the redundant code that turns a led on and off. We'll replace those redundant calls with on and off.

How do we write libraries? define functionality - make a proof of concept - learn c class syntax - implement - debug define the functionality your Library has to provide for our Library we've decided on these functions: on off blink(int time) This should be the premise for our library. At this point, we do not care how the on should work, only that it should exist. Make a proof of concept sketch Before implementing a new class i usually find it very useful to test the idea in a sketch. Try a few different implementations, see what uses the least amount of space, and what seems simplest in use. Select the solution that compromises these two in a suitable way. An experience plan i've made is that if one has something slightly similar to work from, that is often beneficial. For our Library, one immediatly thinks of the Blink right? So, go ahead and start the Arduino ide and open the the first thing we'll do, is to cut the code inside loop and paste it into a new function called void blink.

the functions will be named on and off. I could've selected turnOn and turnOff, but i've selected the shortest because it is as descriptive, but in addition it is shorter. Short code less probability for typos It is important to remember that you do not need a library. It only makes it simpler. If you are interested in the inner mechanics of a specific library, you'll find the mylibrary. Cpp (if downloaded) in /hardware/libraries/ mylibrary / mylibrary. Cpp change mylibrary to whatever the name of the library you want to investigate Why do we have libraries? Simplify usage and/or organization of code Enhance code readability decentralize logic main sketch can now simply state tion instead of coding the equivalent in the sketch.

A library is a collection of instructions that are designed to execute a specific task. Good libraries describe the tasks it tries to solve by the name of the library itself, and the names of the functions associated to the library. This is because the library should be intuitive to use, and all names should describe, in an efficient way, all questions regarding what, when, and where, but should conceal the how. On the Arduino the libraries often serve report as a wrapper around the, arduino api language to enhance code readability and user experience. Arduino ide places it's libraries in hardwarelibraries. The library for this tutorial has the url on my windows xp machine. For the Ubuntu operating system, the libraries may be found at /usr/share/arduino/libraries.
