Output

Output components like LEDs or buzzers do not take an input but instead manipulate their environment.

1 - LED

A LED commonly used with a resistor emits light.
Information

Type : Output

Mode : Digital

Pins : 0-14

Tutorial : funduino

Note: Use with a resistor!

Functions

On

On State

Switches the component on.

void function_0_led(){
digitalWrite(pin_0_led, HIGH);
function_0_led();
}
  
digitalWrite(pin_0_led, HIGH);
  
void function_0_led(){
digitalWrite(pin_0_led, HIGH);
state = 1;
}

Off

Off State

Switches the component off.

void function_0_led(){
digitalWrite(pin_0_led, LOW);
function_0_led();
}
  
digitalWrite(pin_0_led, LOW);
  
void function_0_led(){
digitalWrite(pin_0_led, LOW);
state = 1;
}

2 - Buzzer

A buzzer will emit a sound.
Information

Type : Output

Mode : Digital

Pins : 0-14

Functions

Degree

Turn servo to 0 degree

Turn servo to 180 degree

This function will turn the servo to the degree specified in the function name.

void function_1_servo(){
servo_0.write(0);
function_1_servo();
}
  
servo_0.write(0);
  
void function_0_servo(){
servo_0.write(0);
state = 1;
}
