LED Board App & Guide — Control From Your Phone

Every LED scrolling board we supply can be controlled right from your phone. Most of our boards use the free LedArt app (by Huidu); some use HD sync software. Here is how to change the message on your board in a few simple steps:

1. 1Install the app
   Download LedArt (by Shenzhen Huidu) free from Google Play, open it and allow Wi-Fi / location permissions.
2. 2Connect to your board
   Switch on the LED board. On your phone's Wi-Fi, connect to the board's hotspot (name like HD-xxxx). Open LedArt → Device and it detects your board.
3. 3Create a program
   Tap Program list → New program, then add a Text item.
4. 4Type your message
   Enter your shop name or offer, and pick font, size and colour (red, green, white or full-colour).
5. 5Style it
   Choose an animation effect (scroll left, static, flash), and set speed and hold time.
6. 6Send to the board
   Tap Send — your message appears on the board instantly.
7. 7Set brightness & timing
   In Settings, adjust brightness and set automatic on/off times for day and night.
8. 8Change it anytime
   Reconnect and edit whenever you have a new offer — it takes under a minute.

Exact steps vary a little by controller model. When we install your board we set the app up for you and show you how to change the message yourself — free.
