Why Choose This Project?
Digital signage is widely used in retail, corporate offices, transportation hubs, and public spaces for dynamic content display. By leveraging Raspberry Pi and AWS IoT, students can build a cloud-controlled signage system that updates content remotely, monitors devices, and scales across multiple screens.
This project is ideal for learning IoT device management, cloud integration, and real-time remote content control.

Working Flow
-
Device Registration
Raspberry Pi devices are registered with AWS IoT Core with unique IDs and certificates.
-
Content Upload
Admin uploads images/videos to AWS S3 and schedules them via web dashboard.
-
Content Distribution
Lambda functions notify Raspberry Pi devices of new content and schedule updates.
-
Playback on Devices
Devices download new content and display it on connected screens according to schedule.
-
Monitoring & Alerts
Device status (online/offline, battery, connectivity) is logged to DynamoDB and displayed on dashboard. Alerts are sent if any issues arise.
-
Offline Handling
Cached content ensures uninterrupted playback even when network connectivity is lost.
