How to set up a Public Window

Public Window ( is an open source project which allows artists to display their creations in a window and have people from all around the world interact with it. This is a step-by-step guide on how to set up a Public Window of your own.

A Public Window consists of an artwork connected via an Arduino to a PC with a touchscreen. When someone walks by that window, he or she can than interact with the artwork by pressing buttons on the touchscreen. There are camera’s as well so that the art can be viewed and controlled from another Public Window.

How to set up a Public Window

You will need the following things:

1. A window (or any other place to show your project).
2. A computer with Windows XP or later.

4. An account on (get it here )
5. The Public Window software. Download here:
6. A touch screen (obtain one from here: (link naar de Public Window shop?))
7. An arduino.

Step 2: Connecting the hardware

For connecting the hardware we need to refer you to the manuals for your products.

Step 3: Installing the software

Installing the software

4. Open the file ‘owner.txt’ in the folder you just unzipped. Type your Public Window username in it and save the file.

5. Download and install the Arduino drivers. There is a great tutorial on how to do this on

Step 4: Creating a GUI

Your Public Window will need a graphical user interface (GUI) to show on the touchscreen so users can interact with the art. To do this we have a convenient tool which does not require any programming skills. This is a short guide on how to use it.

1. Go to .

2. Log in with the username and password you received from Public Window. If you dont have it, go to step X in this instructable.

3. You can add buttons, images and webcams with the links under ‘Add items’

4. Your added items will appear in the left window. You can click these items and then drag them to change their position on the screen.

5. You can resize the items by dragging the lower or right edge or the lowerright corner.

6. When you click on an item it’s properties will display on the right side. You can also click on the item in the list and it will appear as well. Here you can change font, colors, background images and assign actions. The action on a button is the text that will be send to the Arduino when the button is clicked.

7. When you are satisfied with your GUI you can enter a name for it in the top right corner of the screen and click on ‘Save GUI’.
