Build the light sword with 3DP+Arduino(用3D列印+Arduino製作光劍)


    I used 3DP and arduino Nano to build the light sword.

There are 4 kind of LED blink modes.Just press buttom to change LED blink modes.
When you wave the sword, it can beep.






Step A:3DP elements
Downlaod 3DP STL file:
http://www.thingiverse.com/thing:1422473


Step B:Electronic and other material:
1.Arduino nano  x1
2.LED                x104
3.power switch  x1
4.buttom switch x1
5.beep                x1
6.virbration sensor x1.
7.18650 battery 2S
8.glue
9.Acrylic tube  1M   x2

Step C:Circuit design & Arduino program.

1:Arduino source code.
Download arduino source code:
https://github.com/Ashing00/sword/tree/master


Due to arduino nano in default only have d3,d5,d6,d9,d10,d11 pin as PWM function.
In order to control the LED brightness so I made the below function to let D2-D9 pin have PWM function.

see the sample code:

//=====PWM sample code======
  t3.every(2, MY_PWM);
void MY_PWM() //2ms  PWM
{
    LEDONOFF(PWM_PIN,PWM_T0);

}

void LEDONOFF(int pin,int t_on) //2ms  PWM
{
 
  if(t_on<=255){
      for(int i=0;i<=255;i++)
     {
      if(i<=t_on){
      digitalWrite(2,HIGH);
      digitalWrite(3,HIGH);
      digitalWrite(4,HIGH);
      digitalWrite(5,HIGH);
      digitalWrite(6,HIGH);
      digitalWrite(7,HIGH);
      digitalWrite(8,HIGH);
      digitalWrite(9,HIGH);
   
       }
      else{
      digitalWrite(2,LOW);
      digitalWrite(3,LOW);
      digitalWrite(4,LOW);
      digitalWrite(5,LOW);
      digitalWrite(6,LOW);
      digitalWrite(7,LOW);
      digitalWrite(8,LOW);
      digitalWrite(9,LOW);
      }
     }
  }


}

//=====PWM sample code======

2.circuit 

 update soon...

 or you can see the source code pin define then understand how to conect 
 arduino nano gpio pins.


The key point:
Use 13 LED  in parallel as a group then connect group 1 to D2 pin.
connect group 2 to D3 pin.
connect group 3 to D4 pin.
.......
connect group 8 to D9 pin.

then just using Arduino nano controll one LED group as one LED.

Step D:Assembe

     Just reference below picture.
Be careful to weld everything.
I used the Acrylic tube  to emhance the sword shell structure.
just glue the each jointer.
