Arduino

Notes on my first Arduino project, a photo booth.

Goal: A photobooth where the user(s) push a button and the camera takes 4 photos and prints a 4x6 that displays the 4 photos on a grid.

Hardware:

  • Sony DSLR A100
  • Basic remote trigger
  • DC Power supply for camera
  • Linux machine
  • Arduino Uno board manufacterd by OSEPP and has a RISC-based ATmega328P microcontroller from Atmel
  • A small, generic breadboard from Radio Shack
  • Soldering Iron (25 Watt)
  • A 2N2222 transistor manufactured by NTE. The NTE part number is NTE123A.
  • 10K Ohm resistor
  • Volt meter
  • Wire strippers
  • 22 guage hook-up wire
  • Printer ???
  • Button

Software:

  • ImageMagick image processing software
  • Arduino development environment

    • With the board set to "Arduino Duemilanove or Nano w/ ATmega328P"
  • Python 2.6.5 and the python-serial package

Circuit:

  • Camera -> Transistor(C)
  • Transistor(E) -> Camera and to Ground on Arduino Board
  • Pin 13 -> Transistor(B)
  • 5V -> Button-> Pin 2
  • Pin 2 -> 10K Resistor -> Ground

Camera Settings:

  • Auto-Focus (not continuous, not wide area, just plain auto)
