Red carpet's project

The red carpet's project was an interactive installation that my company wanted to build for the Christmas party.
Basically the idea was to create a little interactive space where people could walk through this red carpet and some paparazzi would display on the wall.
This wasn't enough to make an amazing experience, so we decided to implement 24 leds around the area where the video was projected and flashed all of them like a real flash.
We also decided to implement an area to take a picture of  yourself and display it into the slideshow.

Video presentation
LEDs matrix
I have builded 6 panels of leds and a big bus of 24 cables to control all leds, I chosen to use a transistor and an external power supply to light all of them, and also a shift register to control them.
This was the shift register with 24 outputs
Each panel have a "home made connector" to make the installation easier and comfortable to carry.

These were 5 panels when I was testing them

Pressure Mat
I have connected 2 pressure mats on my Arduino that have two pins to make it works, one ground input and the output to detect you have triggered it, you can buy them here .
When you step on the first mat the paparazzi movie starts and all 24 leds are starting to flash randomly. And then when you reach the second one, it triggers the count down to make the pose and display it on the slideshow.

Camera trigger
The camera trigger was made with openFramework and the Canon's SDK.
This part wasn't made by me but I have made a similar program with Processing that does the same.
More information about Camera and animation integration are posted to this link

The final installation, its missing some decoration to cover all wires and tapes

We are enjoying the red carpet :)

Even with a lot of people it was a great experience
