Photobooth sample program

[Robert_J_Loomis_III]

Here’s sample code used for a DIY wedding photobooth we built last summer. The physical setup involved an external touchscreen computer, Arduino board controlling 2 relays, and USB webcam. When the user clicks on the orange button (via touchscreen), an event structure is triggered which takes a sequence of 4 images (at 500 ms delay between), stiches them together into a single image, and finishes it off by playing a plays a .wav file and flashing an external light. The computer and touchscreen were mounted into an MDF “photobooth” cabinet.

The Arduino relay turned “on” a desk-type lamp while the pictures were being taken, then turned it “off” at the end of the sequence. A serial connection between the computer and Ardunio sent one of four different text strings indicating which relay to close/open. The Arduino board itself was setup to continuously monitor for these strings, and switch a digital output as necessary.

To test/run it, you’ll need to modify the loop which reads the webcam to suit your particular setup. We used a Sony USB webcam and had the vision development module installed. It was a quick project, so while there are probably much more efficient ways to code it.

Here's a few photos showing photobooth construction (MDF board). The booth was constructed in 3 pieces (top, bench side, and screen/camera side). On the screen/camera side, four holes were cut for (from top to bottom) the lamp/flash, webcam, touchscreen, and speaker grill. Overall dimensions were based on wood we had on hand, and not any particular design.
