There are also some Arduino models out there that include proto board on the PCB so you can solder directly to the Arduino which is handy for this sort of project.

Depending on the connections you get with your particular GPS (any GPS with serial output will work for this project), a small piece of proto board could also be used. The connections are straightforward, but if you are just making this on your bench for fun you might find it easier to use a breadboard. It is probably simpler though to just use an external battery and provide power to both Blink and the Arduino via the USB ports. This port can provide up to 350mA at 5V but only if USB power is supplied to Blink via the mini USB port on the side (the Arduino/GPS combination only uses about 100mA). Whilst we are not connecting the Tip (+5V) to anything, you could actually use that as the power supply to the Arduino, which in turn provides it to the GPS. One of the cheapest ways to get a cable is to just buy an audio extension cable and cut it to the length you require and strip the ends. Note that the colours in the diagram above are indicative only and will depend on your cable. You can use a multimeter continuity test to check.

Take your 3.5mm stereo cable and check which of your bare wires is connected to the Sleeve, Ring and Tip. In addition to this, we need to make the connections to the CamDo Blink controller which are as follows, using the 3.5mm TRS connector.

Technically it can be left floating but for reliability tie it to VCC. 5V power supply eg a V15 or V44 battery if you are going hiking.įor the UBlox GPS used in the parts list, the pinouts and connections are as follows:Įnable Pin.The device is in shutdown mode when voltage to this pin is LOW and enabled when HIGH or floatingĥV.1 x UBlox GPS Module or similar (DFRobot has one with a case).1 x Arduino/Genuino UNO R3 ( genuine ) / ( replica ) or similar.

Both have good background information on the signal interface to trigger the camera, so we won’t go into the same detail in this post.Īll of the code can be found on our Github page here.

Take a photo every x metres (the example we have implemented in this blog post)īefore we get into it, you might also be interested in our post here on How to interface your GoPro to a Radio Control which uses our Bullet controller product to interface to an RC controller or our post here on How to interface your GoPro to a microcontroller (Arduino, ESP8266, etc) using Blink.

Take a photo every x seconds when I am travelling above or below a certain speed.

Take a photo when I am in proximity to a certain landmark.

There are plenty of applications for this, basically any of the data that a GPS can generate (or that you can infer / calculate) can be used. Alternatively you could also set a time lapse controller like Blink to take a photo every 10 minutes and not worry about distance but that’s too simple! It’s not really feasible (or indeed that interesting) to take video of an entire hiking trip, but taking a photo every 500m or 1km is a different matter. I decided to implement a useful tool for bushwalkers or cross country skiers. But instead of a motion detector, we instead use the Arduino microcontroller to trigger it in response to the GPS position and associated calculations. The CamDo Blink enables remote control of your GoPro via the motion detector input. I also came across a 16x2 LCD screen shield for Arduino that I had recently bought from my favourite Chinese supplier websites (DX.com or BangGood) but hadn’t yet tried out.Ī perfect excuse to put both into action. I was looking through my many boxes of parts the other day and came across a UBlox GPS module I had picked up a while ago. I myself had thought about rigging a GPS up to the camera when I went skiing - so it would automatically start filming at the top of the mountain, stop when I stopped, even turning the camera off when it worked out I was now going back up the mountain due to the change in altitude (ie going up hill quite quickly!) and therefore must be on the ski lift. We have received various inquiries about being able to trigger GoPro’s based on a GPS position. Military grade technology in the hands of everyone. Everyone has a GPS these days in your smartphone and they are amazing.
