• G – green component, scope 0 – 100.
• B – blue component, scope 0 – 100.

Rainbow color

Allows you to define the color with just one component. This block is great for generating fluent transitions between colors however, it doesn’t allow for changing the brightness level.

Parameters:

• Color – color value, scope 0 – 100.

Rectangle

Parameters:

• X – horizontal coordinates of the upper-left corner of the rectangle, scope 0 – 7.
• Y – vertical coordinates of the upper-left corner of the rectangle, scope 0 – 7.
• Width – width of the rectangle, scope 1 – 8.
• Height – height of the rectangle, scope 1 – 8.

Example

Display number

Displays a number from 0 to 100 (100 is displayed as 00) in color defined by a COLOR block inserted before it.

Parameters:

• Number – number to be displayed, scope 0 – 100.

Example

Show

Displays previously defined objects (rectangles and numbers) on the display. This block has to be always present to display anything on the display.

Clear display

Clears all the LEDs on the display. Without this block, any new image will be displayed on top of the previous one. In order to display an image or animation on a blank display, you need to clear the display using this block each time.

Example

Connect the potentiometer to INPUT1.
