The LED Screens can be chained together to create a larger screen.
Connect the dout(male)of screen 1 to the din(female) of screen 2
Load the NeoPixel extension.
Initialize the screen with the total number of LEDs(256x2=512).
Pixels 0-255 and 256-511 control screen 1 and screen 2 respectively.
Daisy Chaining can be used alongside matrices. We initialize a matrix with the width of 1 screen.
Using 2 16x16 screens, a 16x32 matrix can be created.
Lighting up the first 2 LEDs of each screen.
Please reference “16x16 RGB LED Screen - Dynamic Effects Tutorial” for details on how to create animations.

The logic is similar to this tutorial, we just change Y to control the 2nd screen.
Example: We add 16 to Y to control the animation on the 2nd screen.
The order of frames may require changing if there are multiple frames.
There may be updates to extensions periodically, please refer to the following link to update/downgrade your extension.
Q: Why is red the only colour lit up when I try to use different colours?

Solution: Reduce brightness or turn on the power on the Robotbit, or connect to a USB power.
Do not connect a power supply with a voltage higher than 5V.
Connect to a USB power supply when for prolonged use.
Lower the brighness when a lot of LEDs are lit.
