Esp32 / NRF24L01 Moodlight

**Smart Object Project** I'm working on a school project that involves creating a smart object. The goal was to design an innovative device using wireless communication or sensors. I decided to focus on wireless communication, even though adding sensors is also an option. **Project Components** To bring this project to life, I needed the following components: - Arduino Nano (or any Arduino board with an SPI bus) - Wemos ESP32 (or any WiFi-enabled chip, like ESP8266) - 2x NRF24L01 Modules - Double-sided prototyping PCB - 1x Female DC Connector - Acrylic diffuser sheet **Mood Light Design** The mood light is a straightforward design consisting of five main components: - The outer shell - The inner ring (for mounting the LED strip) - The reflection chamber (for reflecting light to the outside) - Base Shell - Support from the shell Inside the lamp, you'll find an Arduino Nano, two NRF24L01 Modules, and nine WS2812b LEDs. These components are powered by a 5V adapter via a DC Connector located at the bottom of the outer shell. The base is built around a support generated by a slicer (I used Cura in my case). I wrapped an old sock around it and placed it inside the 3D printer Base Shell to minimize waste. **The Bridge** The bridge is also relatively simple, comprising two main components: - The inner shell (for mounting the components) - The outer shell (for aesthetics) The enclosure houses a PCB with a Wemos ESP32 and an NRF24L01 Module. The ESP is powered by the built-in Micro USB Connector. **Expandability** Since the design is clean and versatile, you can repurpose it as a module with a speaker inside, creating a sleek Bluetooth speaker.
