I’m using the Arduino Uno and this sketch assumes you’ve connected the circuit to pin 7 to control the shutter. Once you have this basic circuit, you can connect it to the Arduino board. I’ve set R2 higher than the calculated value because I was planning to use the circuit mostly in low light conditions and didn’t need the indicator to be super bright. The arduino pin will be 5V when the shutter is triggered, so use 5V for the source voltage and take the other values from your LEDs spec sheet. There’s a handy online calculator which helps with this. The values of resistors R1 and R2 should be tailored to provider the correct current to your particular opto isolator and LED. This is optional but can be useful in practice. I’ve found it convenient to add an indicator LED to the circuit to show when the controller is activating the shutter. There are many others available too which work similarly. I’m using a 4N35 opto isolator because I had a couple already available and it’s a decent choice for a general purpose job like this. The camera side of the circuit is kept electrically separate from the Arduino side, with light being the the only link between the two. This is essentially an electronic switch which uses light to isolate two circuits, while allowing the circuit on one side of the opto isolator to control the other. I’m using an opto isolator in my circuit too, to control the shutter. The Arduino board is used to control my circuit in order to fire the camera in bulb mode. For now, we’ll ignore the focus connection and just deal with the shutter.

I’m working with the canon N3 type of connector but if you search online you can find plenty of info for other connector types.įor Canon N3, the connections when looking at the camera are:Ĭonnecting the focus pin to the common ground pin is equivalent to a half press of the shutter button whereas connecting the shutter pin to ground is equivalent to a full press. At a basic level, this just involves connecting two of the pins used for the camera remote together, to simulate pressing the button on the remote. The core of this project is a simple circuit which connects to the camera’s remote shutter release. The potential rewards were worth it for me but if you’re going to follow me down this route, you need to accept that risk for yourself too. This isn’t intended to be a complete solution to everything you could possibly want to do but rather a primer on taking those first steps along with with some pointers and ideas on where to go next.īefore I go any further I guess I need to make it clear that in doing this I was prepared to accept the small risk of damaging my camera in some way in order to learn and create.

If you’re interested in doing a similar project, I’ve documented some basics here to help you get started.

An equally strong aim is simply to teach myself about both Arduino programming and what’s involved in using it to control my camera, partly just out of interest and partly so I have the knowledge and flexibility to be able create hardware and software of my own design. There are ready made timelapse tools available such as the excellent ‘ little bramper‘ but I’m at the point where I’m finding it useful to be able to add some custom hardware and software to my timelapse toolkit.

One aim for me in this little project is to create a controller which I can program to help with the job of shooting timelapse sequences.
