This is a good idea that could help newbies who are always having trouble understanding how to install libraries!

Hi Renato,

Today all my stuff going to Italy for next year from here (Saudi Arabia) is going on the truck.

Couple more days and I can Think. (As we used to say in IBM ...)

Hi,

Take a look at:
http://www.arduino.cc/playground/Code/Library

Which is Alexander's tutorial on Libraries.... Well done!

Hello Renato,

Wow, you have been busy with this..

I am convinced this will be the way to go for sophisticated Arduino applications such as 24-7 Automation for Home, and other controls such as Garden/Hydroponic systems etc, etc.

I will write up my notes on a scheduling concept later today and maybe we can discuss that further.

I am in the throes of packing my Lab and other belongings that will be shipped to Italy for next year, and the Arduino stuff I will bring back to the US for the Summer. In a couple days that will settle down and I will be writing more...

The combination of non-blocking functions in your RTOS and efficient and easy to set up scheduling (A scheduled Time is just an Event, right?) will make many cool applications possible.

Hi Oscar,

By that time we will definitely have even more Educational material and Courseware that you can use.

For now, take a look at a few things:

What Can I DO with an Arduino: http://yourduino.com/whatcanido.htm

A Quick Start with Arduino:  http://yourduino.com/get-an-arduino.htm

How to Get Started With your Arduino:  http://arduino-info.wikispaces.com/GettingStarted-Software

I am working with a couple of teachers now on Course materials for young people...

Any suggestions or pointers appreciated!

Shielded CAT 6 sounds very good for this.  Best if you use the flexible stranded-wire versions, from a vibration perspective.

OK, so I'm not going to lie... I'm very new to ARDUINO, and have very little progrraming experience. But I've set my mind on a project and need some help getting there... 

Welcome, and you are exactly the kind of person that the Arduino Community needs... 

We'll be following your project.

Tell us more about the Sensors...
8  Using Arduino / Project Guidance / Re: Using Arduino 2560 board with only my C-language code and arduino boot on: June 02, 2011, 08:39:28 am
Hi,

I would start by looking at how people are integrating code written in C and C++ into libraries:
http://www.arduino.cc/playground/Code/Library 
Alexander knows LOTS more than I about this ....

...but those libraries have code that gets linked by the AVR stuff inside the Arduino IDE setup...

Also another Library tutorial:

matrix Orbital MX232 usb lcd
 

Is this really a "RS232" driven display with a USB interface??

Arduino can not act as a USB host without significant software development and a "USB Host" shield added...

11  Using Arduino / Project Guidance / Re: help with approach for automated testing equipment code on: June 02, 2011, 06:21:02 am
Hi,

Is this going to run a similar type of test with the same applied distance and same maximum force?

Or do you want to make a more general testing system that can be used for a variety of tests.

If it's more like Rob suggests,

-move the mechanical actuator over a range in some size of step(s),
- record force at each step
- stop at maximum force OR distance 
???

Ah, but where's the fun in that? 


Exactly, the fun is in figuring out how to do it with Arduino with class.  Also buttons. Also flashing LEDS.

I do believe Arduino can solve most problems.  I tried to nominate Arduino to be the official arbitration element in the Middle East situation.  It could do a lot better than the present players. Right now, people are getting shot and killed North, South(35 yesterday), East and West of where I am.  So It's not an idle speculation. 

But the kids in school here are not allowed to discuss "the situation" at all. If they did they would have to mention that country that starts with "I", which is not even on the maps here. 

I'm so glad we have freedom to talk here. Even OT. 

2 weeks and I'm Outta Saudi Arabia on a short hop to Cairo. Shortly after that I'm headed to the Atlantic, New York, Vermont.

Phewww!!

I can't wait to get to my Log Cabin in the woods, turn on my scope and plug in an Arduino. 

13  Using Arduino / Project Guidance / Re: adding a time interval to a PIR sensor on: June 01, 2011, 12:23:35 am
Hi,

If the sensor is like this one:
http://arduino-direct.com/sunshop/index.php?l=product_detail&p=173

That little orange pot is a minimum time when fully Counter Clockwise.  But that may still be too long??

So, in code, wait for the sensor to come on, fire the Whatever for however long you want, then wait for the sensor to go OFF, then repeat??
14  Using Arduino / Project Guidance / Re: electric hot water controller - Thermar? on: June 01, 2011, 12:19:33 am
Hi, Interesting project...

So, I think I understand this:

1. Reed switch / magnet senses water is flowing. (Does this cycle on-off like a rotating magnet, or stay on??)
2. Thermistor senses output water temperature
3. SSR is cycled to control water temperature.

So the Arduino has a pretty simple job:

- IF Water is flowing enable the temperature control  (Otherwise make sure no heating happens!)
- IF Temperature control is enabled, monitor temperature with thermistor, cycle SSR appropriately.

(This implies you have a way to set the desired temperature. Can be a simple external Potentiometer that you later calibrate.)
Or "His" and "Her" buttons?  (You have to decide what to do if "Both"  smiley  )

As in that saying from the 60's "Save Water .. Shower With a Friend".

Later you can control your wood stove...

Let us know how it goes....

Hi Stephen,

I have used the Mindstorms motors with H-bridge like your L298.. They are run from 9V in the original RCX h-bridges. You can run them from 9V and also use that to run the Arduino through the external power jack. 6 AA rechargeables might be good.

Someone has a complete analysis of the Mindstorms motors on the web; http://www.philohome.com/motors/motorcomp.htm

The NXT motors, I believe are run by signals from the controller... I2C?? Anyone??  More info here: http://www.philohome.com/nxtmotor/nxtmotor.htm

Let us know how you are doing with this....
