The OBEGRÄNSAD LED wall lamp presents an opportunity to blend technology with creativity. By modifying this device, users can transform it into a dynamic drawing canvas, enhancing their visual experience. This article outlines the essential steps to adapt your lamp for displaying art and information.
Before proceeding, it is vital to recognize the risks involved. Modifications should be approached with caution, as improper handling may damage the device. Always take responsibility for your actions and consider community feedback for potential improvements.
Getting started with your project
To initiate the project, ensure you have the necessary equipment and software for your OBEGRÄNSAD LED wall lamp. This project primarily supports ESP32 Dev Boards, but with some adjustments, it can also work with other Arduino models. After establishing a connection, the built-in web graphical user interface (GUI) facilitates easy control of the lamp.
To find the device’s IP address, consult your network settings. Once located, connect to the lamp to begin the configuration process. Focus on the lowest plate of the lamp, which consists of four identical layers, each housing 64 LEDs. This arrangement will be crucial for connecting the necessary pins as detailed in the project documentation.
Essential components and setup
The lamp is assembled using rivets instead of traditional screws, making access to internal components slightly more challenging. After gaining access, follow the included instructions regarding pin configuration in the include/constants.h file. If you prefer to use the original button wiring, additional connections are not necessary; community insights, such as those from RBEGamer, can assist in this process.
To continue with the project, clone the project repository. The PlatformIO tool will automatically manage dependencies, simplifying the setup. Connect your ESP32 board to your computer and configure the project settings as outlined in the documentation. This includes building the project and uploading it to your device.
Wi-Fi setup and over-the-air updates
For the ESP32, using a Wi-Fi manager is highly recommended to streamline network configuration. Upon booting, you can modify the network name using the WIFI_MANAGER_SSID parameter found in the include/constants.h file.
If you are using an ESP8266 board, manual settings will be required. You must enter your Wi-Fi credentials directly into the include/secrets.h file. Regular Over-The-Air (OTA) updates enable you to wirelessly upload new firmware without needing a USB connection. This is facilitated by the ElegantOTA library.
Before utilizing the OTA functionality, ensure you have configured OTA credentials in the include/secrets.h file and adjusted the upload settings in the platformio.ini for the appropriate environment. Replace the placeholder IP address with your device’s actual address to ensure proper connectivity.
Visual feedback and troubleshooting
During OTA updates, the LED matrix provides visual feedback, allowing you to monitor progress through serial output. If issues arise, the established base URL can be used to access device information, current status, and available plugins.
