Creating the application in Evothings Workbench. You can find the Arduino sketch in the Evothings Gallery repository. So in this sketch, each pulse contains a 120 milliseconds high (5V) followed by a 70 milliseconds low.
We found that we had to increase each period with 20 milliseconds gave the camera a better chance detect the correct signal. So basically the application receives a number from the BLE link and then outputs the pulse an equivalent number of times on pin 3. As it turns out the number sent from the smartphone happens to correspond to the number of pulses that the camera needs to detect in order to execute that command. For the camera to detect one pulse it has to receive a signal that is 100 milliseconds high (5V) followed by 50 milliseconds low (0V). In zoom mode the camera counts the number of pulses it receives on the USB-port. These commands were encoded according to the following table. We chose to use the camera in zoom mode meaning that there will be five commands available (1) zoom-in single step, (2) zoom-out single step, (3) shoot, (4) zoom completely in and (5) zoom completely out. In this application, the Arduino expects to receive single-byte messages which will be decoded to certain commands. The Arduino application will receive data via the BLE Shield and translate it into commands. Note that the RedBearLabs BLE shield is missing in this drawing. Our cable ended up looking like this:Ĭamera cable connections on the Arduino. In order for this example to work, you will need wire #1 (red) and wire #4 (black) as explained in CHDKs Homemade USB Remote Cable instructions. Since we figured that we will experiment more with USB Remote triggering at some later point we simply made a prototyping cable by cutting an ordinary cable and soldering pins onto each wire. Setting up your cameraĮnter the CHDK menu and then navigate to CHDK Settings -> Remote Parameters.

The CHDK community provides a great tutorial on how to do that, you can find it in CHDKs ‘Prepare Your SD card’ guide. You will need to prepare your camera with the latest version of the CHDK.

Over the years we have used the software to experiment with timelapse photography and used the enabled functionality to learn more about photography in general.Ī couple of months ago, a friend of ours announced that he was get married this August. The project is mainly focused on point-and-shoot type of cameras. For those of you who are not familiar with their work, they develop a firmware that enables extra features for supported Canon cameras. We have been avid users of Canon Hack Development Kit (CHDK) since we first discovered their work many years ago. In this tutorial, we use an Arduino Uno and a mounted ReadBearLabs BLE shield. BLE goes at least 50 meters, even without an external antenna.
You probably already have a phone, and adding an off-the-shelf microcontroller is an inexpensive way of getting it all together, and with many degrees of freedom. Controlling a camera from an Arduino micro-controller opens up a world of possibilities for us mobile devtool guys from advanced time lapse, to nature shots of shy game, who keeps stealing from the cookie jar to astronomical observations through a telescope-mounted camera.
