How to make a scrolling LED sign on iPhone

Before you begin

Write the message before choosing effects. A name, greeting or short announcement is easier to read than a full paragraph, especially when the viewer has only a few seconds.

Step by step

1. Open LED Banner and create a new text design.
2. Enter your message and choose a readable font and text size.
3. Set text and background colors, then preview the scrolling display.
4. Adjust speed until the complete message is easy to follow and save the design.

Check the result

Hold the phone at the distance where you expect people to read it. Check the entire sentence, not just its first word, and confirm that nothing important disappears too quickly at the edge.

Limits and troubleshooting

If the display feels busy, shorten the wording before adding more effects. The app uses the phone's screen; it does not control an external LED board or make a small screen readable from any distance.
