There is no need of support in any part except in body.

Schematics

Circuit diagram

It's not that difficult, if you know how to connect a LED and a push button with arduino. You can easily do this too.

Connect LED on pins -1,3,4,5,6,7,8,9,10,11,12,13,A0,A1,A2 and A3
connect push button on pin 2
Connect power on VCC and GND pin

All done!!

Code

LED effect

Arduino
This code contains only one effect and that's why I am not using push button as well
int LED[] ={0,3,4,5,6,7,8,9,10,11,12,13,A0,A1,A2,A3};
int Max= 16;

void setup() {
  //pinMode(mode, INPUT_PULLUP);
  for(int i=0; i<Max; i++){
    pinMode(LED[i], OUTPUT);
  }
  }

void loop() {

  for(int i=0; i<Max; i++){
    digitalWrite(LED[i], HIGH);
    delay(50);
  }

  for(int i=0; i<Max; i++){
    digitalWrite(LED[i], LOW);
    delay(50);
  }
}
