Controlling the onboard LED matrix and RGB LEDs on the Arduino UNO Q

The Arduino UNO Q has an onboard LED matrix and RGB LEDs.

You can control their display using the blocks in the "Display" - "Arduino UNO Q" group.

Initialization

After connecting to the Arduino UNO Q, use the initialization block to initialize the LED matrix and RGB LEDs.

Displaying Bitmaps

You can display bitmaps on the LED matrix using the display bitmap block.

Show bitmap

Clicking on the bitmap allows you to set the on/off state of individual pixels.
Black indicates on, white indicates off.

Display Grayscale Bitmap

Using the grayscale bitmap display block, you can display a bitmap with 8 brightness levels specified for each LED.

Show grayscale bitmap

The brightness of each LED is represented by an 8-level numerical value from 0 (off) to 7 (on).
There are 104 LEDs (8 rows x 13 columns), so the bitmap is represented by arranging 104 numerical values from 0 to 7.
It can be represented in the following two ways:

A string containing 104 numbers from 0 to 7 separated by commas (newlines can be included)
A list containing 104 numbers from 0 to 7 as elements

Scrollable Text

You can scroll and display alphanumeric text on an LED matrix.

The "direction" parameter determines the direction in which the text scrolls.
The "speed" parameter specifies the time in milliseconds (= 1/1000 of a second) it takes to scroll one pixel horizontally.

If you specify long text, it may take more than 10 seconds to finish scrolling.
Executing a process that takes more than 10 seconds will result in a timeout error.
Therefore, if scrolling takes more than 10 seconds, increase the value of the "Timeout" parameter to extend the time before the timeout occurs.

Clearing the LED Matrix

The Clear block can be used to turn off all LEDs in an LED matrix.

Turning on RGB LEDs

The Arduino UNO Q has four onboard RGB LEDs.
Each LED can be lit by specifying its color.
