Road Signaling Controller Board for Tri-Vision Billboard Systems

Challenge: An outdoor advertising company needed a precision controller board for large tri-vision prismatic billboards (several meters long) with motor-driven rotation mechanisms. The key requirements were precise advertisement alignment, selective control to disable specific advertisements when needed, and synchronized operation when multiple billboards were installed side by side.

Solution: I designed a custom controller board featuring:

• Precise motor control for accurate prismatic alignment
• Communication protocol for multi-unit synchronization
• Manual override switches for selective advertisement control
• Weather-resistant design suitable for outdoor environments
• Simple operation interface for field technicians

Technical Implementation:

• Microcontroller-based control system with identical boards for scalability
• Simple wired network for synchronized multi-unit operation
• Configuration switches for customizable behavior
• Robust outdoor-rated enclosures

Results: The solution enabled the company to enter the market with both single-unit installations and complex multi-billboard synchronized systems, significantly increasing their market reach and installation capabilities.
