What you can build

If it needs a big, friendly button, this is the one.

Wiring it to Arduino

Do not connect the 12V LED to an Arduino pin. Power it from a 12V supply. To turn it on and off from your code, switch it through an NPN transistor or a logic-level MOSFET, and join the 12V supply ground to the Arduino GND.

Basic Arduino code

Each press toggles the LED on pin 9 (through your transistor or MOSFET) and prints a message in the Serial Monitor.

const int buttonPin = 2;
const int ledPin = 9;
bool ledOn = false;
int lastState = HIGH;
void setup() {
  pinMode(buttonPin, INPUT_PULLUP);
  pinMode(ledPin, OUTPUT);
  Serial.begin(9600);
}
void loop() {
  int state = digitalRead(buttonPin);
  if (lastState == HIGH && state == LOW) {  // button pressed
    ledOn = !ledOn;
    digitalWrite(ledPin, ledOn ? HIGH : LOW);
    Serial.println(ledOn ? "LED ON" : "LED OFF");
    delay(30);  // simple debounce
  }
  lastState = state;
}

For a USB spacebar button, use an Arduino Leonardo or Pro Micro and this sketch:

#include <Keyboard.h>
void setup() {
  pinMode(2, INPUT_PULLUP);
  Keyboard.begin();
}
void loop() {
  if (digitalRead(2) == LOW) {
    Keyboard.press(' ');
  } else {
    Keyboard.release(' ');
  }
  delay(10);
}
