//Blink code:
// int is type of variable. variables are where we store information.
// here we store the name of our LED pin.
int led = 13;
// another variable as an example.
int blinks;
// the setup routine runs once in the beginning.
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
// initialize the serial port monitor
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(100); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(100); // wait for a second
blinks = blinks + 1; // add one to the variable blinks.
// Send the value of blinks to the serial port monitor.
Serial.print("Blink # ");
Serial.println(blinks);
