I add a tiny bit to what Phi wrote.<br>
<br>
IMO, the easiest way to realize the fish tank project is this. But
requires Linux/Unix knowledge<br>
if you don't have it better to stick with Arduino and the serial
port.<br>
<br>
Buy a BeableBone Black/Green (just like Rpi, but better for
electronics). Plug a screen into it, install Cuis there. <br>
Buy I2C sensors. Read stuff via I2C.<br>
The Cuis part would be only to: 1) send shell commands to Linux
underlying to get I2C data 2) display stuff<br>
graphically. <br>
<br>
If you want complex graphics, logs etc it can take a while,
otherwise from the point of view of Cuis<br>
it is not difficult.<br>
<br>
After that, it may become a bigger project if you want to reach you
fish tank data when<br>
you are out of the house via mobile phone.<br>
<br>
Anyway, this is the "dream" application. For now let's focus on
arithmetics ;) <br>
<br>
From the point of view of the Cuis part of your project i would say
intermediate goals are:<br>
1) read data from file [or generate random data]<br>
2) in the World put some labels saying: <br>
Temperature | X1<br>
Light | X2 <br>
etc.<br>
3) Have the values X1, X2 ... X3 update every second (reading from
file or from random data)<br>
<br>
<br>

<div>My .02 is to go with the fish tank idea. It's something
you have so obviously care about. A big part of programming
is sticking with and many people have a problem staying
focused to see projects through. Having a goal you really
care about helps dramatically with keeping your motivation up
and actually finishing it.</div>
<div><br>
</div>
<div>You're probably thinking right now about maybe keeping a
log and graphing it which would be a great starting point.
However, you could do much more with it (just google 'arduino
aquarium') if you were interested... all being
monitored/controlled from Cuis. Doing software + hardware
projects is even more work so if that interests you, think of
it as a long term project and just start with the software
side of it for now. (if you end up going down the hardware
path, start with monitoring hardware as some of the automation
stuff can be dangerous to the fish if you make a mistake. So
wait until you develop a level of confidence in your skills
before going there.)</div>

For programs, the first thing I can think of is making a fake
ATM machine, don't have anything else really in mind yet. I
don't think my mind has fully expanded to appreciate the
language to pick other projects. The other I can think of
actually would be making a program to track my fish tank
parameters (ammonia, nitrities, nitrates, PH, GH, KH and
temp). That would be really cool as well. <br>

Hi Joseph,<br>
<br>
Define a little program you would like to write.<br>
<br>
E.g. The first program i really wrote because i wanted it
was an alarm playing a certain mp3 <br>
at increasing volume in the morning. Probably it was a
Bash script. I wrote some C code<br>
before that, but it was for univ. assignment, not the same
thing, at all. <br>
<br>
This is the best way to learn anything, keep a target in
front of you, a problem to be solved ;)<br>
<br>
To learn Smalltalk takes some time because it is a system,
not just a programming language.<br>
To me it took time to wrap my mind around it and still i
am not that advanced.<br>
TheCuisBook is a book about the Smalltalk SYSTEM called
Cuis. It takes in a LOT of stuff. <br>
Digest it slowly. Use other sources as well, ask
questions. <br>
<br>
The first things you must understand are: variables, loops
and tests and the most basic kind<br>
of objects like Strings and Numbers, List, Date etc. Focus
on that ! Explore the "TereseGuide". (TerseGuideWindow
openTerseGuide . )<br>
Work in the Workspace and Transcript. Forget defining new
Classes for the moment, use<br>
what Cuis has already defined for you. <br>
<br>
Don't change dialect, if you start jumping from Cuis to
Squeak to Pharo to esleTalk you will get extremely
confused.<br>
<br>
Don't give up, this is the most beautiful way you can use
a computer.<br>
<br>
Maybe in the next weeks I may have time to put online a
video tutorial about the language,<br>
which is actually the easiest part of Smalltalk. OOP is
your friend, you will see, it is there to<br>
make things simpler. <br>
<br>
bye ;) <br>

<blockquote type="cite"> No problem. As for a other mini
update. I'm still for the most part having to look at
the solutions. Maybe I'm not very good with smalltalk.
Maybe its OOP I can't understand, but I really don't
feel like I'm learning much. I am in no way saying its
an issue with the book, it just might be at a level that
is not basic enough for me. I would like to hear what
peoples thoughts are on this. Maybe its OK that I'm
looking at the answers? <br>

You mentioned about me looking for anything in the
book, and I do have one thing to mention. Some of
the exercises are kinda difficult and I've had to
goto the solution. Most of them made sense after
looking at the solution, but some of them I don't
understand. For example.<br>
<br>
Exercise 4.9<br>
<br>
($A to: $Z) collect [:c | (c asciiValue - 65 + 3 \\
26 + 65) asCharacter] .<br>
<br>
I have no clue how that math calculation works at
all. <br>
