Variables in Uiflow are always set to global, which is one thing to keep in mind if programming. To make the M5Stack listen to keypresses while counting I used MicroPythonвЂ™s built-in _thread library which sadly is not available as a predefined block. Not every function from MicroPython is implemented in Uiflow, but you can get around this using custom вЂexecuteвЂ™ blocks and writing your own code.

Uiflow is a bit different, as you вЂњprogramвЂќ your code using predefined blocks and Uiflow creates micropython code out of it. You can also have more than one script on the M5Stack and select the desired program during startup. If you use Uiflow, the code can be updated wirelessly. I first tried to program with the amazing M5ez library, but the M5Stack has a very neat feature that I wanted to keep. The total cost for all of this was about в‚¬50, or about $60. Of course, you need a cable that suits your camera or, like I did, just use the cable from a timer that I already had. (The pictures above do not show the current state of his Timer.) for a very good experience when using the timer for its main purpose: timelapse shooting.

It looks just stunning, has a very powerful preset system, and is very easy to set up as it calculates movie lengths, times, etc. Markus was kind enough to send me this version and I installed it on my just-delivered M5Stack. I contacted Markus to get the Arduino code since the link was broken on his website, and he showed me the current status of his timer, which looks really polished with really nice graphics and a super sleek user interface. A small enough housing with integrated LCD, buttons, battery, and charging circuit. While looking for other options I came across a project from Markus Kail, which looked promising.

If I build something, I also want to mess around with the code. There are smaller Versions now available through the LRT Forum but the one I am interested in, is closed source at the moment, and that doesnвЂ™t fit my style. I could have just built a LRTimelapse Remote Timer Free but I dislike the 2Г—40 Display, the outdated Arduino Uno, and the size of it.

Gunther Wegner, the man behind LRTimelapse, also has a very nice tutorial on how to build your own intervalometer, which exceeds my build by miles in terms of features. With a price of around в‚¬175 (~$206), it is not on the cheap side, but I guess itвЂ™s worth every cent.

There are a bunch of other people creating more complicated devices including this one on Make, but again what I like about this set up is that it is easily adapted to other uses.The only off-the-shelf intervalometer that looks like a winner is the LRTimelapse Pro Timer 2.5. The device takes a picture every 5 seconds. I modified the вЂњBlinkвЂќ example sketch that comes with the Arduino IDE to turn on for 0.5 seconds, off for 5 seconds.

To get it to take timed exposures I connected the circuit to pin 13 and GND on the Arduino and plugged the shutter cable into the camera.

Just to be extra cautious I put a resistor and diode on the camera side of the circuit as well. Just like you need a resistor in series with your LED you should have one with the opto-isolator. The control side(Arduino) turns on the LED, the controlled side (camera) lets current through the phototransistor when the LED is lit, thus the electrical circuits are isolated. An opto-isolator is basically just a LED and a phototransistor packaged in a IC.

This is because I didnвЂ™t include the resistors. The first couple of times I tried this I fried a few opto-isolators. The camera focuses right before shutter release anyways. I didnвЂ™t bother with the focu for my version. If you connect the shutter and common pins the shutter is set off, if you connect the focus and common pins the camera focuses. There are three pins, one is common, one is shutter, one is focus. Nikon uses a mini jack.Д¬anon and Nikon have different hookups for the shutter cable but they use basically the same set up. This proprietary plug is why you have to buy a cable.
