OMG! IT BLINKS!

Mr. Editor

Arduino code

// ( )

void setup(){ // }

void loop(){ // }

Blink Arduino, blink!

void setup(){ pinMode(LED_BUILTIN, OUTPUT);}

void loop(){ digitalWrite( LED_BUILTIN, HIGH); delay(1000); digitalWrite( LED_BUILTIN, LOW); delay(1000);}

Lets add a variable

int led = 13;

void setup(){ pinMode(led, OUTPUT);}

void loop(){ digitalWrite(led, HIGH); delay(1000); digitalWrite(led, LOW); delay(1000);}

Can we go faster?

int led = 13;

void setup(){ pinMode(led, OUTPUT);}

void loop(){ digitalWrite(led, HIGH); delay(100); digitalWrite(led, LOW); delay(100);}

The world is analog

Blink another LED

Blink another LED

Night light (sort of!)

Night light (sort of!)

int led = 11;

void setup(){ pinMode(led, OUTPUT);}

void loop(){ int light = analogRead(A5); analogWrite(led, light);}

Whats going on inside?

int led = 11;

void setup(){ Serial.begin(9600); pinMode(led, OUTPUT);}

void loop(){ int light = analogRead(A5); Serial.println(light); analogWrite(led, light);}

Its getting hot
