Story

Anybody wonders one day to make a photo booth in any event. Actually a couple of days ago there was for the first time in Egypt "Cairo Mini Maker Faire" event, where around 3000 makers all over Egypt came to celebrate this event. I tried to implement a low cost, fancy and easily to be implemented photo booth.

In this project, you will find a full description for the bill of materials and the dimensions of the booth and in the video, you will find the time lapse for implementing the photo booth from scratch.

Hardware Implementation

Actually, the circuit implementation is so simple. I have build the circuit on Fritzing. All you need is ultrasonic sensor and relay with AC lamp.

Regarding the Photo booth, you will find an image with the whole dimensions of the PVC pipes and in the video you will find how we implement itself.

Arduino Sketch

Actually, as shown below the code is straight forward. We always checks the value of the ultrasonic sensor and whenever it becomes less than 40 cm, we will blink our AC Lamp 3 times as an indication for the capturing, then the camera will capture the image and finally the mobile will post the image on twitter. Just one line of code for capturing and another one for tweeting.
