Then you need an event to activate the remote shutter. The other (violet) cable is connected to an I/O pin. Option 1: without transistor WiringĬonnect the GND cable (blue for me) to GND of the Arduino. As a strain relief, I attached the cables to the lower cover with some superglue. I did this in the places outlined in red, as shown above. File a recess in the top cover or use a Dremel tool to do this. Alternatively, do as I did and continue to use the housing. You can use the board without a housing, but you have to make sure that the battery has fixed contact, or you use an external power supply (3.7 volts). Opened remote trigger with cables connected to the pushbutton under the small button Feeding the cables through the housing If you are not sure, measure the resistance between the contacts and this GND contact. Another GND connector is highlighted in red in the right image. Note that the position of GND at the pushbutton under the large button (picture right) is reversed from the pushbutton under the small button (picture below). The contact on which the blue cable is soldered is also GND of the remote shutter. I took jumper cables for this, which I cut off on one side.

Bridge them on a trial basis and observe when the LED lights up. With a wire or similar you can check which are the relevant two of the four contacts. A sharp knife with a sturdy blade is suitable for this purpose. Preparing the remote shutterįirst, you carefully (!) open the case. The preparation of the remote shutter is the same for both paths.

The latter, however, also has a disadvantage that I still have to come to. The method has been described here before, but I found a simpler way, with one less solder connection and no transistor. I am not the first to come up with this idea. The next idea was to bridge the button of the remote release in a suitable way so that it can be switched from the outside. Hacking the remote shutter and switching from the outside

#Arduino camera timer trigger Bluetooth#

I myself am still looking for an understandable introduction to the subject.Ĭonclusion: A (simple) emulation of the remote shutter by a Bluetooth module is not possible. You can change the firmware (instructions here), but then you would still need to familiarize yourself with the HID profile. And this does not work with the firmware present on the Bluetooth modules. The remote shutter communicates according to the HID (Human Interface Device) profile. What is relevant is that not every Bluetooth device or module can communicate with every other. 1 second (can be changed in the smartphone settings)Īs I had to learn myself, there are various Bluetooth profiles that build on the general Bluetooth specification or other protocols. long press: triggers continuous shooting after pressing for approx.short press: a blue border appears around the trigger button on the smartphone, each further press triggers a photo.

Although one is labeled iOS and the other Android, both work with my Android smartphone: Then you start your smartphone camera app. Bluetooth is probably turned on by most of you in these Corona times anyway. You need to turn on the remote trigger and pair it with your smartphone. I bought the model pictured on the right. Remote shutters – ready-made solutionsīluetooth remote shutters for smartphones are available for a few euros at Amazon, for example.

In the next post, I’ll show you how to use Bluetooth modules like the HC-05 or HC-06 as remote triggers, giving you much more flexibility.

Control without Arduino, for example only with a motion sensor.

Solving problems in long-term operation.

Hacking of a remote shutter and control with the Arduino (Uno).

The whole thing then got so big that I ended up splitting the post into two parts. In hindsight, this is a good example of supposedly simple projects spinning out of control as you go from one challenge to the next. My first thought was that this would be easy. This could be used to build a camera trap, for example. It all started with a simple reader’s question about whether a Bluetooth module like the HC-05 or HC-06 could be used to simulate commercially available remote shutters for smartphone cameras. In this post I’m going to look at remote shutters (also called remote triggers).
