A recent project demonstrates the creation of smart bracelets designed to help long-distance couples stay connected using ESP32 microcontrollers. The bracelets utilize the Ubidots IoT platform to facilitate communication between two devices, allowing partners to send signals to each other from anywhere in the world.
Each bracelet is equipped with an ESP32 module, which manages the device's operations and connectivity. The project employs SquareLine Studio for designing the user interface, enabling customization of display elements such as images and animations. The interface is tailored to show personalized visuals, like an animated image of the partner, enhancing the user experience.
The bracelets communicate through the Ubidots IoT platform, which acts as a bridge between the two devices. This setup allows for the exchange of "love signals" and monitoring of a counter value that tracks interactions. The counter value is stored in non-volatile memory, ensuring data retention even when the device is powered off.
The project also includes features such as a reset button to clear the counter and the ability to control vibration motors, providing tactile feedback to the user. The use of the ESP32's Wi-Fi capabilities ensures that the bracelets can communicate over long distances without the need for direct Bluetooth connections.
This DIY approach offers a customizable and cost-effective solution for couples seeking to maintain a tangible connection despite physical separation. The project's reliance on open-source platforms and readily available components makes it accessible to individuals with basic electronics and programming knowledge.
