1  Using Arduino / Project Guidance / Re: Uno controlling DMX lights from 3 PING ultrasonic sensors? on: October 08, 2012, 03:04:35 am
thanks for the suggestions awol and Id3300 ~!~

i am going to go buy the Guildenstern DMX shield , http://shop.trinculosattic.com/products/the-guildenstern-arduino-dmx-shield

which says it works with the UNO. Coding will be the next step and im sure i will ask for help on that soon enough. I may use PURE DATA as way to use PROCESSING , but that will require the computer, though my ultimate goal is , like you said to be totally run on arduino. thanks For the enthusiasm i am PSYCHED!!! This will be s0o0o0 fun!
My first attempt will be to use the DMXsimple library with the UNO and Guildstern DMX shield. We'll see what happens smiley


here are some additional angles of the concept design

Here is a helpful Graphic for wiring  several ping sensors to the uno

Can my UNO drive DMX lighting as is, or do i need a
SK PANG DMX shield http://www.skpang.co.uk/catalog/arduino-dmx-shield-p-663.html
or a
Guildenstern DMX shield http://shop.trinculosattic.com/products/the-guildenstern-arduino-dmx-shield ?

I watched This video about controlling DMX lights with Arduino through PureData

 a few months ago and being totally new at the time didnt notice it was not an UNO. Long story short i bought and am learning on an Uno. Then, heading over to the DMX arduino Playground   http://www.arduino.cc/playground/DMX/Opendmx i see the phrase "All this just works with an old arduino board, since the UNO there is a different chip used smiley-sad"

Oh what a scary statement!

Do i need to buy a  Arduino Duemilanove ?

THank you for your responses.... this makes Art happen smiley)

THank you Hal-

it is what it is.  having 6-10 measurments per second ...if it can deliver an emotional effect, then we have succeeded.

would either of these scenarios work help to create more measurments per second

=-=-Scenario A=-=-=-
removing the walls  so its just posts creating the box and supporting the sensors. and creating a ignore ping response > 50ms (aka 10 inches or whatever) to create the "ultrasonic edges" of the box

=-=-=-Scenario B=-=-=-
Some type of Foam can absorb ultrasonic waves to deaden the echo

how did the installation go, kato?

I am just getting started with arduino , and am learning day by day. Ive gotten some leds to blink in a row, and performed basic calculator functions.

so i have a month to pull off an amazing project I here it is:


have a box with 3 ping ultrasonic sensors located on 3 of the walls (X, Y, Z)

and map those values with an arduino UNO to DMX out represented by RGB values (and thus changing the color of the room)

placing your hand in the box, the closer your hand got to that sensor, the more of that color value would be sent to the lights, the the room becomes more of that color.

so say
(input of PingX =  output of DMXLED RED)  // Hand far away from sensor, 0 red, hand up to sensor 100% aka 255 RED

(input of PingY = output of DMXLEDGREEN) // Hand far away from sensor, 0 green, hand up to sensor 100% aka 255 GREEN

(input of PingZ = output of DMXLEDBLUE) // Hand far away from sensor, 0 blue, hand up to sensor 100% aka 255 BLUE



so with the mix of RGB you can make so many colors by waves of a hand! an interactive station smiley)

ive got about a month to pull it off, and i come here on my knees humble for assistance. Thank You in advance smiley
