Hello Listers~
I'm working on an art gallery installation and I want to use Pd to control some high-powered LED's via an Arduino unit.
The breakdown is this: I need to create a series of RGB LED's that will provide accent illumination to the gallery space, and shifts from red to blue over a course of 6 weeks. The program isn't very difficult to write. I've already decided to link it to the system date/time so that the installation can be powered down easily at night. What's tricky is knowing what hardware to use and how to get it together. I am going to want between 25-100 lights at minimum, possibly more.
I've looked at a few sites and links already, especially the Arduino site. They have some things related to DMX lights, and this is something I've seen a bit on the list as well. I don't know if this is a good solution or if it is overkill for what I want to do.
One piece of hardware that seems promising is the ShiftBrite ( http://www.macetech.com/blog/node/54). Does anyone know about this?
I know this might be considered off-topic, but I'd really appreciate it if any seasoned veterans could throw me some tips. I'll be exploring other areas, but I know there are some honed brains skimming these emails so maybe they can drop some science on me.
Thanks in advance,
~Kyle
Hi Kyle,
For an installation for the LAC 2008 I used a Midibox (http://www.ucapps.de/) with a special custom digital output controller (with optocouplers and power transistors) to control up to 64 (I used 48) 3W power leds. I used Pd to control that over MIDI, and I added to the Midibox firmware the posibility to use PWM to control the leds bright.
I'm terrible sorry to Frank Barknecht and Martin Rumori about my still pending documentation, as the last year I was in a hurry between several projects... But I still want to do it, so... I can start with the hardware part, that I'll try to do on the next week, but anyway, if I can help you with something specific just write me. Basically, with an Arduino you could do the same, you just need some power /isolation (to use an external power device for the leds) interface.
Well, I'll send the link when I'll publish the circuit.
Best regards, Natanael.

Hey Kyle
Sounds like a really cool project.
Are you sure you need any special hardware at all? You could use the PWM out from the arduino and a transistor for each set of LEDs you want to control then build an array. A friend just showed me this ridiculously cool site: http://led.linear1.org/led.wiz
I'm talking like I've done this before, but really I'm only part way through a similar process, so maybe it's all totally wrong:) Anyway, hope it helps.

i think, i'd do it the same way. i've done it before, but not in that large scale. Of course, one could purchase an expensive professional coloured Ligthing-LED-System with very expensive dimmable power supply units and sophisticated control-protocols such as DMX or DALI or whatsoever, but when not being afraid of a little soldering, you could achieve pretty much the same with anarduino, a handful of electronic pieces and plain LEDs from your local electronic store. actually, when using an arduino it is pretty straightforward to do something like that.
i wouldn't use common transistor fors driving the LEDs. i'd rather go for MOS-FET transistors. you could drive a whole bunch of LEDs with one MOS-FET and they draw nearly no current from the arduino digitalOut. also, as long as you work with low-voltage, you don't necessarily need de-coupling such as opto-coupler or so.

Hi,
I got 32 channels of PWM using two tlc5940 connected to several
uln2003. Actually i found someone had a circuit diagram too.
Here we go. If you dont ever have all 100 on this might work using
some multiplexing too. There is a library for arduino written for this
chip. I can send you the code i used if you go this route.

Ayah Bdeir used an Arduino with a custom Firmata firmware to run a
shift register and a matrix of LEDs. The code and the circuit is here:
http://www.makingthingsmove.org/blog/
A little bit of work needs to be done to add shift register support to
the Pd side of Firmata (Pduino), but I'd be happy to do it if you'll
use it. Its already on my todo list.

Using ReBirth is like trying to play an 808 with a long stick. - David Zicarelli
Blinkm ( http://thingm.com/products/blinkm ) also work well since you control them over i2c thus simplifying wiring, but there more expensive then a standard led.

Thanks so much everyone for your prompt replies!
This is going to be a quick job, the opening is the 2nd Friday of February. It's a group project and many in the group are hesitant to use LED's. The requirement is to have it be task lighting but also low-light. The gallery is not huge, I'd say about 1000-1500 square feet.
Could this be accomplished with LED's? How many should I use. Also, are there any other ways of doing this, using lighting other than LED?
Thanks so much for your replies, I'm a newbie at lighting-design so I'm a bit nervous about coming through with an elegant solution for this project!
