Toggle Switch

I wanted to figure out how to use a toggle switch with Arduino! I looked around online and compiled a few different things to get this.

Toggle Switch Code

arduino

The basic code. It uses the digital pins on the board.

1int switch_pin = 4;
2int led_pin = 5;
3
4byte leds = 0;
5
6void   setup() {
7  pinMode(switch_pin, INPUT);
8  pinMode(led_pin, OUTPUT);
9}
10
11void   loop() {
12  if(digitalRead(switch_pin) == HIGH){
13    digitalWrite(led_pin,   LOW);
14  }
15  if(digitalRead(switch_pin) == LOW){
16    digitalWrite(led_pin,   HIGH);
17  }
18
19}

int switch_pin = 4;
int led_pin = 5;

byte leds = 0;

void   setup() {
  pinMode(switch_pin, INPUT);
  pinMode(led_pin, OUTPUT);
}

void   loop() {
  if(digitalRead(switch_pin) == HIGH){
    digitalWrite(led_pin,   LOW);
  }
  if(digitalRead(switch_pin) == LOW){
    digitalWrite(led_pin,   HIGH);
  }

}
