Camera Time-lapse rig
An Arduino controlled camera time lapse rig that has an on/off switch and limit switch
An Arduino controlled camera time lapse rig that has an on/off switch and limit switch. It is designed to trigger the shutter on a Canon camera via the N3 connector, i guess it could be easily changed for a Nikon.
There are 4 LEDs. Blue = system running, Red = system paused, Yellow = shutter release, Green = motor moving.
The shutter release is isolated from the powered Arduino side of the circuit using a photocoupler.
