Hello. I was wondering how I could make an LED blink and then stop it, when pressing a certain key on the keyboard. Similar to a power switch. Any ideas for a source code ? Thank you !

Yes you can but my advice it's the same from my other partners (paul and shabaz). I can put here a little piece of pseudo-code to guide you.
bool last_state_on = false;
void setup(){
pinMode(pin_to_stop_blink, INPUT);
pinMode(pin_led, OUTPUT);
}
void loop(){
if(digitalRead(pin_to_stop_blink) == LOW) //ACTIVATE IN HIGH {
if(last_state_on == false){
last_state_on = true;
digitalWrite(pin_led,HIGH);
}else{
last_state_on = false;
digitalWrite(pin_led,LOW);
}
}else{
digitalWrite(pin_led,LOW);
}
}
The code is tooooooo simply but i think that for the first step is better go piecemeal. If you continue with Arduino you will discover a many things to improve in this code.
Try by yourself

You might need to add a delay in the code as well, otherwise the blinking will occur too fast to be perceived by the human eye.
