Great idea with the traffic light. Combine programming an Arduino with 3D
printing lessons.
A two night/day project!

I agree Simon, there are definitely parallels between the traffic light
control and train club. I thought of that too.
I attended train club a few times, and those guys are actually making a
lot of progress with their train track. They are basically trying to do
exactly what you described. They still have a lot of work left, but they
are definitely making progress from what I seen last time!
I think there is a train club meeting tomorrow. You should definitely
check it out, its cool stuff!

I know we have people talking about a model railroad club but
don't actually know if anyone's doing anything in it...
...But it seems like a neat task might also be to make a similar
controller for a model railroad? For instance, if we could make a
little setup with two trains going in opposite directions on the
same track, with a little switching station with photo sensors to
let them pass by each other automatically? (Though that might be
the advanced class.)

1) An IR LED and photodiode to sense beam breaking. This could
be tested with this from RadioShack, although we can get
better quantity pricing elsewhere:

2) a CdS photocell the car passes over. Like 1), but using
room light as the source.

Geno,
I like your application idea a lot! I would be happy
to assist in
printing the traffic light enclosures on my printers
at home as well.

*Subject:* [hackpgh-discuss] Basic Arduino Programming
Class
I looked at the previous Basic Arduino class HackPGH
did in the
past, and I would like to cover all the topics from
the class we
did in the past, but to keep things interesting every
year,
present them in a different way.
My idea is this. We 3d print 2 of these for all the
students.
http://www.thingiverse.com/thing:14646
The student brings their own arduino (which they got
and soldered
together at the soldering class), or just one they
already have.
The object of the class will be to control two traffic
lights at
an intersection. First just with timing, and then to
introduce
the ADC input and map() function to have a small
sensor which
would make the light green if a car just arrived at an
intersection (like many real traffic lights at quiet
intersections do)
This will teach the student about basic arduino
concepts such as
I/O and timing functions such as delay(). In the
advanced course
we can introduce how to use interrupts for timing. And
it will
teach the students the basics of ADC and very very
basics of
sensors, which they can learn more about in the
sensors class.
This can actually be a cool practical toy for your
kid's RC cars
or hotwheels. They could even build real intersections
for a
small toy city. I really wish I had this when I was 9. ;-)
If anyone has suggestions on how to make this class
better, ideas
to make the traffic lights more cool, or even better
3d printed
traffic lights we could download, that would be awesome!
This class will most likely take place in April
(definitely after
learn to solder)
