Alternatively, search for mBlock in an app store to download or update it.

4. Program xLight
(1) Tap Back to coding.
(2) Set the coding mode.
mBlock 5 provides two coding modes, namely Upload and Live.
Live: In this mode, you can execute the program you've written in real time. During program execution, you must keep xLight connected to mBlock 5.
Upload: In this mode, you need to upload the program to xLight before you execute it. You don't have to keep xLight connected to mBlock 5 during program execution.
For example, set the coding mode to Upload.
(3) Drag blocks to the scripts area.
For example, we can write a simple program to light up the LEDs of xLight assembled with the wooden base and keep changing the brightness of the LEDs.
Note:
If you program xLight assembled with the LED strip or LED string, use the blocks in the LED Strip or LED String category.
(4) Click the Upload icon to upload the program to xLight.
After you upload the program to xLight, xLight lights up the LEDs in red and the brightness keeps changing.
Note: The control box of xLight can store only one user-defined program. A new program you upload to it replaces the last one.
5. Switch between the user-defined program and default program
You can switch between the default program and user-defined one by continuously pressing the button three times.
For details about the default program, see Default Program of xLight.
