Invervalometer

Arduino based intervalometer for time lapse photography

Arduino based Intervalometer project. There are a number of projects on the internets that provide this functionality but I wanted to add settings tor days and time periods in addition to a more traditional time lapse interval.

Original code is for Arduino Uno, but will eventually allow for compiling against other chips. (Adafruit Feather for example)

Development environment

• Visual Studio 2015 with Visual Micro (Arduino IDE V 1.6)
• Arduino IDE 1.6.11 compiles and uploads successfully

Libraries

• DS3232RTC http://github.com/JChristensen/DS3232RTC
• TimeLib http://www.arduino.cc/playground/Code/Time

Requirements

• Set interval between shutter/photo capture
• Set length of exposure
• Set number of exposures per capture
• Allow day of week control - e.g. don't shoot photos on Sunday
• Allow on/off time period - e.g. only shoot between noon and 6pm

Current hardware

• ATmega328P/Arduino Uno (includes adafruit pro trinket and metro mini)
• Real time clock DS3231 (https://learn.adafruit.com/adafruit-ds3231-precision-rtc-breakout/overview)
• Nikon 5100 (you can modify as needed to your camera)

Future Functionality

• Configure via wifi or BLE
• Logging events to SD card, wifi or mobile/3G/4G
• Upload photos to some where
• support other boards/processors and RTCs

Electronics components

• See wiki for details about what transistors and resistors are needed
• Camera remote controller - for Nikon 5100 it is MC-DC2

Configuration

To set up the code to compile and use the right settings for your board you need to edit the lib_customizaation.h file to set the #defines macros.

You can control a led indicator with

#define _FLASH_LED_ON_TRIGGER

The first time you compile/run, set this flag to truw bool gForceClockSet = true;
Once the clock is set then change that flag to false.
