Arduino Lightsaber

This project is made to simulate a Light saber from Star Wars by using an Arduino Nano. This repository includes the Arduino code, the diagram and a pcb design

Materials

Materials that I used to make the Light saber:

• Arduino Nano
• WS2812B LED strip
• Push button
• 330 Ohm resistor
• Resistor (1KOhm recommended)
• 4 AA 1.5v (rechargeable) batteries
• 4 AA battery holder

Diagram

Code

Before you upload the code to your Arduino, you should have the following libraries installed:

• FastLED
• OneButton

At the beginning of the code you will find a section to customize your Light saber:

// ------ Settings ------
#define LED_PIN       8
#define BUTTON_PIN    5
#define NUM_LEDS      50
#define DELAY         1

bool orange = true;
bool green = true;
bool red = true;
bool white = true;
bool purple = true;
bool yellow = true;
bool blue = true;

bool flickering = true;
// --------------------

• You can change the pin numbers if you want to, but there is no need to if you have followed along with the diagram.
• NUM_LEDS can be used to change the length of your Light saber
• DELAY can be used to change the speed between each transition
• You can disable any color by changing the boolean to false
• flickering can be used to enable or disable flickering

How to use

• With a single press on the button the LED will go on/off
• With a double press on the button you can change the color of the LED
