Digital Crackers as a Sustainable Alternative: Designing a High-Decibel, Emission-Free Firework Simulation Using Node Mcu

Using digital crackers be a part of modern, digital India, a step closer towards sustainable and safe health-focused Diwali. This study investigates the use of digital crackers instead of fireworks, which cause a lot of air and noise pollution. Digital crackers utilise advanced technologies such as AR, VR, IoT-based devices, and LED-based simulators that not only ensure a safe, reusable, and eco-friendly experience but also provide a rich usage experience. Here, we propose a Node MCU-based prototype to mimic firework effects with visual as well as auditory effects without producing any emission of pollutants and low noise. Data was collected on the prototype energy efficiencies, noise impact, cost-effectiveness, and user perspective under a controlled environment. Findings showed digital crackers offer potential to be an eco-friendly alternative to the bursting of traditional firecrackers while garnering widespread user acceptance, suggesting these can be mainstreamed to shape future festive practices.
