I would appreciate a copy also.  Thanks.

I'm sure these questions have been addressed mutiple times, but i would put both in General Electronics.


I will search that forum first and post if needed.  Thanks.

Questions like
How do I build and connect an external pwm controller for 2A to my Arduino?
How do I connect multiple i2c devices to my Arduino?

What forum would be appropriate?
4  Using Arduino / Interfacing w/ Software on the Computer / Thread on Stack Overflow on RXTX and alternatives. on: March 15, 2014, 11:10:39 am
I'm new to Arduino and working out how I will do IO from various Linux systems to
USB/FTDI connected Arduinos.  To that end, I've been going through this forum
and found this Stack Overflow thread with a survey of alternatives.  I thought this
might be helpful to others as well.

5  Using Arduino / Project Guidance / Re: Demonstration code for several things at the same time on: March 13, 2014, 05:43:51 pm
If you want get advice about the SimpleTimer library (about which I know nothing) I would appreciate it if you would start a new Thread as I would like to keep this thread to the one subject so as not to confuse newcomers.

...R
I'm not looking for help with SimpleTimer, sorry.  I'm learning how to multiple things on an Arduino myself., just not starting  with the same demo.  I will continue watching this thread.

I'm assuming you have JRuby installed and know where to put the jar / how to make the program find it.

Yes and thank you.

I have prepared the attached example sketch in the hope that it will be a
suitable model. I have tested it on an Uno and a Mega. I have called it
"SeveralThingsAtTheSameTime.ino". (It seems to be too long to show the
code directly in this post)
...
It also uses the "state machine" concept to manage the various activities
and enable the different functions to determine what to do.
...
Comments are welcome.

Thank you for this, I will be studying it.

I'm new to Arduino coding and learning what and how can be fit in Arduino
IDE code.  My starting approach was to leverage this SimpleTimer code:

http://playground.arduino.cc/Code/SimpleTimer#.UyIPih_f9ic

Here is a code fragment where I do periodic Serial writes.  This not
really equivalent to what your code is doing, but this is my starting
point.

Code:
...
#include <SimpleTimer.h>
...
SimpleTimer timer;
...
void setup()
{
...
  timer.setInterval((5*1000), timerWrite);
...
}
void loop()
{
...
  timer.run();
...
}
// Periodic write to Serial to test RPi <-> Arduino
void timerWrite()
{
  // Code here that queues up some text to write on Serial
}

I originally wrote the Python program in JRuby as I am more familiar with that. I can provide the JRuby version if anyone is interested.

I'm a JRuby developer, I'm interested.  Here is a project I did.
