Esp32 / NRF24L01 Moodlight

# **NRF24L01 Mood light** This is for a school project of mine. The objective was that you had to make a smart object. This can be achieved by adding wireless communication or with the help of sensors. I choose to go for wireless communication even though sensors can easily be added. **Parts used in this project** - Arduino Nano (or any Arduino 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 <h2>Mood Light</h2> The mood light is pretty simple. It consists of five components: - The outer shell - The inner ring (for mounting the led strip) - The reflection chamber (for reflecting the light to the outside) - Base Shell - The support from the shell Inside of the lamp is the Arduino Nano, the NRF24L01 Module and 9 WS2812b LEDs. These are powered by a 5V adapter via a DC Connector located in the bottom of the outer shell. The base is built around the support that is generated by the slicer (In my case I used Cura). I added an old sock around it and put it inside the 3D printer Base Shell. This way no support is wasted. <h2>The Bridge</h2> The bridge is even simpler. It consists of two components: - The inner shell (for mounting the components) - The outer shell (for making it look good) The enclosure contains the PCB with the Wemos ESP32 and the NRF24L01 Module. ESP is powered by the built-in Micro USB Connector. <h2>Expandability</h2> Because the shell is very clean it doesn't have to be used for a lamp, you could also make a module with a speaker in it and you have a very nice looking Bluetooth speaker. -Steven Slaa
