Creating a dynamic time-lapse using a microcontroller
Once, I had a Canon Soap Dish and it had a mini jack input. Through which the interferometer could be connected to the camera and the timelaps could be removed. Intervelometer is such a thing that can automatically press the trigger with a specified time interval. That's what I did then.
And everything was fine, but the era of mirrorless mirrors came, which were better, faster, faster. Therefore, I happily bought a mirrorless Sony. However, the usual hole in it was not, and my intervalometer was useless. Googling, I learned that the manufacturer does not provide a wired connection, and there are only primitive consoles that you need to shine into the camera with in front. Having reproached Sony for the user friendly interface, I remained for several years without a time-lapse.

Recently looking at YouTube, I came across programming material for arduino, and I was surprised to find that it does not need to work with processor registers in assembler, but everything is written in C ++ and there are ready-made libraries for different occasions. And I thought that ...
There were a lot of thoughts to do, but I tried to think of something useful. Such that someone else wanted to repeat my device.
The time-lapse device seemed like a great idea. Initially I wanted the camera during shooting and moved and rotated. But then I thought that the platform for movement would make the device too large and heavy and a normal person would not take it on vacation. Therefore, I decided not to move.
Then I began to choose components. I took the Wemos D1 as the main controller, because it is software-compatible with the Arduino, and at the same time it has wi-fi and more memory on board. The idea was to control the device from a phone browser.
To rotate the camera took the cheapest and most common stepper motor and controller. And to control the shutter of the camera is an infrared LED.
The body decided to make 12 mm plywood. Because, firstly, it is rather heavy, and this is good for stability, and secondly, I had it. Within a month, the ordered parcels arrived to me and the process started ...
To build and flash the program to the controller, I used Platformio, and CLion as the IDE. I did not find the specification for the infrared interface of my camera, but I came across a ready-made library for Arduino, which does what I needed. And at the same time, she also knows how to control the shutter of cameras from different manufacturers. So, thanks to the developer, I implemented the choice of the camera manufacturer in the application, although I was not going to do it. I added a little library to simplify the work with different cameras in one application.
Then of course there was a long and pleasant time-lapse shooting. And Ta-Da !!!
"Open source project, described everything to the maximum, the source code posted. Thanks for attention!
