Create an EPIC Treasure Hunt Using BLE Beacons

Learn how to create an outdoor location-based treasure hunt using ESP32 and Bluetooth Low Energy (BLE) beacons in this 15-minute tutorial from Playful Technology. Discover how BLE beacons positioned at specific locations broadcast unique IDs that can be detected by an ESP32 device, advancing players to the next clue when found. Unlike GPS systems, Bluetooth doesn't require line-of-sight to satellites, allowing you to design hunts that work indoors, outdoors, or even underground. The tutorial covers connecting an ePaper display to the ESP32 via SPI interface to show clues with both text and images, including photographs and maps. The video walks through introduction and demonstration, Bluetooth and ESP32 hardware requirements, game design considerations, detailed ESP32 Arduino IDE code implementation, wiring diagram setup, and concludes with a summary of the project.
