“Hi Everyone! My name is John Lukito, and I’m a second-year student at Binus University studying Computer Engineering. I am thrilled to be working on this project alongside my talented peers, Michael Angelo Chandra and Johevin Blesstowi, who are also pursuing the same major. Together, we aim to delve into the fascinating world of the RGB LED cube and explore how cloud connectivity can enhance the functionality of this captivating device.
An 8x8x8 RGB LED cube is a visually captivating electronic device. It consists of 512 individually addressable RGB LEDs arranged as an 8x8x8 cube. Each LED can independently emit red, green, and blue colors, allowing for a wide range of vibrant color combinations and dynamic lighting effects. By controlling the brightness and color of each LED, intricate patterns, animations, and even 3D images can be created.
In our project, we aim to integrate cloud connectivity into the 8x8x8 RGB LED cube to explore the benefits it can bring. By connecting the LED cube to the cloud, we can leverage the power of the internet and remote devices to trivialize the animation selection process. This connectivity will enable us to access a vast library of pre-defined animations or even create our own custom animations using cloud-based tools (on-progress). Additionally, cloud connectivity can provide real-time synchronization, allowing the LED cube to display animations on-demand, creating a responsive and easy-to-use experience.
With the combination of the 8x8x8 RGB LED cube and cloud connectivity via Firebase, we aim to push the boundaries of creativity and interactivity in lighting displays. By harnessing the power of the cloud, we can tap into a virtually limitless array of animations and dynamically control the cube’s visual output. Stay tuned as we embark on this exciting project step-by-step and build one for ourselves.
