Arduino push button/LED/ not in sync

Hello. The problem is, every time i push my button down, the Arduino fails, the LEDs aren't doing what they're supposed to do, and if I try to upload the code again, it says that it is not in sync.

Ive used the right COM port and the right board.
If i remove the push button, it works just fine. The sound reactive LED that is.

The LEDs use 5V and there are 60 of them. The resistor is 10k ohm.

Here is a link to my setup:

Here is the code:
(Ignore the // because it's in my own language)

//Hetta er eitt savn, sum hendan kotan er tilgjørd eftir. 
#include <FastLED.h>

//Hvønn pinn LED DATA/DIN pinnurin er koyrdur til í Arduino.

//Hvønn pinn ljóð sensor A0 pinnurin er koyrdur til í Arduino.
#define ANALOG_READ A0
//Hvussu nógvar perur eru í LED reimuni.
#define NUM_LEDS 60
//Hvat slag LED reimin er.
#define LED_TYPE WS2812B

//LED skipanin. Hetta er í fylgi FastLED savninum.
CRGB leds[NUM_LEDS];

//Hvønn pinn knótturin er koyrdur til í Arduino.
int switchPin = 3;
//Virði á støðuni hjá knóttinum. 
int val;
//Støðan hjá knóttinum.
int buttonState;
//Hvussu ofta tað er trýst á knøttin.
int buttonPresses = 0;

//Kotan, sum verur koyrd ígjøgnum einaferð.
void setup()
{
  //Hetta ger so upplýsingar koma frá knóttinum, og til Arduino.
  pinMode(switchPin, INPUT);
  //Her lesa vit støðuna hjá knøttinum av.
  buttonState = digitalRead(switchPin);

  Serial.begin(9600);

  //Hetta tekur #define's omanfyri, brúkar FastLED savni, koyrir tað saman og inní Arduino.
  //Hetta er tað, sum ger at LED reimin at lýsa, og sum eisini ger at honn kann innstillast. 
  FastLED.addLeds<LED_TYPE, LED_PIN>(leds, NUM_LEDS);
  //Hetta petti rakar øll ljósini í LED reimuni, og verur ofta brúkt.

  {
    //Í hesum førum raka vit øll LED ljósini, og skifta lit.
    leds[i] = CRGB(0, 255, 0);
  }
  //Her er eitt delay, sum syrgir fyri at kotan higartil er stabil. 
  delay(1000);
}

{ 
  //Her verur sagt at val skal vera virði, sum verur lisið av.
  val = digitalRead(switchPin);

  if ( val != buttonState)
  {
    //Um val er LOW, so hendir kotan niðanfyri.
    if (val == LOW)
    {
      //Hetta økir talið eftir hvussu ofta man hevur trýst á knøttin.
      buttonPresses++;

      Serial.print(buttonPresses);
    }
  }

I know the code can be optimized, but it was working just fine before. It isn't too slow, it doesn't matter I think.
After trying to upload again, I get the not in sync error. I also tried different Arduinos, different ports, and diffirent USB cables.

Also, the red ON light is working at all times. The green L light is on when i power up the Arduino. But as soon the LED goes to red (the startup color) the light goes rouge. If i manage somehow to change the LED to a different color, maybe blue, the green L light is dimmed, or fully on.

Any help is appreciated.

Ok thats way more LED's than the board can handle.

Consider a seperate power supply for the LED's with a common ground to the Arduino.

Bob.

Are you sure? Seemd to work fine 2 days ago

Quite sure !

The regulator on the board is only capable of so much and you are more that likely past that limit.

60 times 60 mA =3,600 mA
Now look at the limits for the regulator if you need further proof.

There are plenty of other post about similar issues if you want to take a little time to look up issues involving multiple LED's and power issues.

It may be you have simply weakened the regulator circuitry to the point it might fail.

Look up addressable LED circuits and notice all the GOOD schematics show two power rails.

Many also mention the limits as well as the reason behind the need for two supply rails.

Bob.

Additionally.

Input Voltage Limits:

Recommended: 7~12V

Absolute: 6~20V (to ensure longer board life never go to the max level but stay in the 7-10 volt range)

Input/Output (I/O) pins: -0.5V to +5.5V (the actual max is “Vcc + 0.5V,” which for a 5V Arduino, is +5.5V)

Output Current Limits:
When powered by USB: total of 500mA

With external battery or power supply: total of 500mA~1A (as with voltage try stay a little below max although it will generally only draw what is required)

5V pin: same as above: 500mA or 500mA~1A (see above)

Each input/output pin: 40mA (use amplifiers or buffers of some type if you need more)

Sum of all input/output pins combined (but NOT including the “5V” pin): 200mA.

Bob.

Thank you. I'll try hooking it up with a different power supply that can hold the limits.
