co2-sensor — Arduino Uno simulation

An interactive Arduino Uno circuit simulation you can run free in your browser on Velxio, by gfn.

Sketch code

// Arduino Blink Example

int led1 = 13;
int led2 = 12;
int led3 = 11;

void setup() {
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
}

void loop() {
  digitalWrite(led1, HIGH);    // LED 1 an
  digitalWrite(led2, LOW); 
  digitalWrite(led3, LOW);      // LED 2 aus
  delay(6000);

  digitalWrite(led2, HIGH); 
  delay(2000);

  digitalWrite(led1, LOW);     // LED 1 aus
  digitalWrite(led2, LOW);
  digitalWrite(led3, HIGH);     // LED 2 an
  delay(6000);

  digitalWrite(led2, HIGH);
  digitalWrite(led3, LOW);     // LED 2 an
  delay(2000);
