The visual programing tool allows you to create code by assembling blocks like puzzle pieces.

The basic structure of a program is given by the following two Kniwwelino blocks :

Kniwwelino on start contains the blocks which are only executed once, at the start of Kniwwelino (for instance the variables initialisation).

Kniwwelino repeat forever contains the blocks which are executed repeatedly, while Kniwwelino is powered.

All blocks available are organised in categories. In this section you can get information an all available blocks and how they can be used. Click on the image to get more information on the blocks available in that category.

Category	Description
	Blocks you need to program the 5×5 red lights in the middle of your Kniwwelino. For instance, you can show an icon or a text. ...more
	Blocks you need to program buttons A and B on the Kniwwelino. In addition, there are blocks to program external buttons that can be attached on the Kniwwelino pins. ...more
	Blocks you need to program the RGB light above the matrix. You can select the color, brightness and effect. In addition, there are blocks to program external LEDs that can be attached on the Kniwwelino pins. ...more
	Blocks you need to send and receive messages via Wifi. You can, for instance, send an icon or text to another Kniwwelino....more
	Blocks related to logic, such as if-then conditions, or the comparison of two numbers. ...more
	Blocks you need to create variables, i.e. placeholders to hold a value or a text and reuse it later in your program. ...more
	Blocks you need if you want to repeat a same piece of code multiple times. ...more
	Blocks related to numbers and mathematical operations on numbers, such as addition, substraction, but also rounding or generating random numbers. ...more
	Blocks you need to create text or do operations on text, such as concatenating text ...more
	Blocks you need to control time in your program, for instance to let Kniwwelino wait before the next block, or to get the current date or time. ...more

To compose your program, you need to connect one block after the other. Drag and drop the blocks to connect them. As soon as you see a yellow mark, you can connect them.

To delete a single block, you can either:

• Drag and drop it to the bin

• Right-Click on it and select 'delete block'

• Or select it and press 'delete' on your keyboard

If you want to delete all blocks, click on the bin on the top right of the window.

You can duplicate blocks by either

• Right-clicking on the block and selecting 'duplicate'

• Or selecting a block and using the shortcuts 'ctrl+c' and 'ctrl+v'

To transfer your code to the Kniwwelino, press the orange play button.

Beware: before using this button, be sure to have made all the required Preparations.

To save your program on your hard disk, open the menu accessible from the top left. With the save button you can save the code as an xml file on your hard disk and open it later with the open button.

You can change the language also from the menu (see previous point).

If you need more information on how to use a specific block, you can right-click on the block and select 'help'. It will open the related page from this documentation website.
