Customizable Arduino Nano LED Candle (2 - 6 LEDs)

thingiverse

This is a detailed guide on how to build an Arduino-based LED candle that can be powered by a 9v battery. The project involves creating a custom 3D printed base, assembling the components, and programming the Arduino Nano. Here's a step-by-step breakdown of the guide: **Printing the Base** 1. Download the STL file for the base from Thingiverse. 2. Print the base using a 3D printer with recommended slicer settings (0.1mm - 0.2mm resolution, 10% - 20% infill, no supports or rafts). **Assembling the Components** 1. Bend the LED pins and wires to one side. 2. Tie the LED wires together using a cable tie. 3. Use electrical tape to secure the wires to the underside of the LED mount. **Gluing the Diffuser** 1. Apply a small amount of hot glue to attach the diffuser to the LED mount. **Using the Project** 1. Attach a 9v battery to the base. 2. Insert the LED mount into the base, ensuring that the 9v battery and Arduino Nano are sitting inside their respective compartments. **Printing Settings** The recommended printing settings for the base are: * Resolution: 0.1mm - 0.2mm * Infill: 10% - 20% * Supports: None * Rafts: None **License** The model is licensed under CC BY, and the code is licensed under The MIT License. **Alternative Code** If you'd like to try a different code, you can use the "flickering-flame" code from GitHub. This code uses an exponential low pass filter to enhance the effect and is designed for 5 LEDs but can be adapted for a different number of LEDs. Overall, this guide provides a detailed instructions on how to build an Arduino-based LED candle that can be powered by a 9v battery. The project involves creating a custom 3D printed base, assembling the components, and programming the Arduino Nano.
