#Arduino camera point and shoot code

CHDKlover came up with the idea to write a script that looks for the length of time that the pulses on the USB port is high or low.īy combining this in a smart way quite complex signals could be transmitted to the IXUS. It is a kind of morse code that can be sent. Ok so that is very nice but i would like to do more. The resulting PCB you can find below and you can also purchase them from the shop.Ĭomplex IXUS remote using arduino (many functions) I came across some USB connector which were perfect for making a small PCB which allows the above function. You can now use any button on any IR remote control to operate the camera. You use the same very simple CHDK LUA script as above. I used my arduino to deliver 5V but you can also use a battery source.Ĭonnect the battery 5V to both PIN1 of the TSOP1838 and the red USB wire.Ĭonnect battery ground to PIN2 of the TSOP1838.Ĭonnect TSOP1838 PIN3 to the black USB wire. If you open up the IXUS960IS there is a USB port This is where the circuit should be connected to. The USB port usually has wires with the colours red, green, black and white and they are normally connected as per the diagram below. In our circuit we only use the red and black wires. So how should we wire the thing together. Fortunately this does not matter as the result of taking a picture is achieved. The rest of the signal is missed because the IXUS firmware is busy doing other things. When the signal is driven high and the USB port is powered the IXUS is driven to take a picture. We can use this in our CHDK remote control.

Eventually the signal exits the receiver and comes out as a series of pulses. The signal is modulated at about 38kHz to suppress the surrounding IR light for example coming from the sun.

I used the TSOP1838 which i also used for decoding the remote control signals using the arduino. Below you can see how the IR signal from the remote control is processed in the receiver. The next step was to look at using a IR remote receiver. Using a TSOP1838 as a button (take picture only) This worked fine but needed a USB cable between the switch and the IXUS960IS. In practise this is rather inconvenient because the cable gets in the way and you are also restricted as to the distance you can cover. Initially i used a simple switch like the reset button on the arduino. The CHDK IXUS remote LUA script is really simple for taking a picture as shown below.

So i will use two cells with a diode to drop down the voltage in series for my final circuit. I did have to experiment a bit with the battery as with me a 3V cell battery did not work. Using 5V from the arduino was fine. There is a page dedicated on this on CHDK. The idea is for the switch to power the USB power line on and off and use the get_usb_power statement in the scripting language to detect this and operate the camera. You only need a very simple button and battery circuit like below to make this happen. Of course i wanted to make a remote control so that i could take pictures at a distance. Simple button ixus remote (take picture only)

I have a IXUS960IS which is the camera i used to test all that is stated here. Check it out here. This page will not delve into CHDK itself as you can read all about it on the CHDK pages. It stands for Canon Hack Development Kit and offers a huge range of additional features. What i especially like is the ability to add scripts with which you can add new features to the camera.

(eg your TV remote) To operate it needs CHDK which is a firmware that you can load into many canon cameras. This article is about making an IXUS remote control to be able to take pictures using any standard infra red remote.
