Arduino Testing - Andrea & Nick

Our three variations in Arduino featuring videos of each with the code.

1) Blink Speed
Code:
// the setup function runs once when you press reset or power the board void setup() { // initialize digital pin 13 as an output. pinMode(13, OUTPUT); pinMode(9, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(100); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(100); // wait for a second }

2) Alternating
Code:
// the setup function runs once when you press reset or power the board void setup() { // initialize digital pin 13 as an output. pinMode(13, OUTPUT); pinMode(9, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(200); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(200); // wait for a second digitalWrite(9, LOW); // turn the LED on (HIGH is the voltage level) delay(200); // wait for a second digitalWrite(9, HIGH); // turn the LED off by making the voltage LOW delay(200); // wait for a second }

3) Counting
Code:
int count = 0; // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin 13 as an output. pinMode(13, OUTPUT); } // the loop function runs over and over again forever void loop() { count++; for (int i = 1; i <= count; i++) { digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(200); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(200); // wait for a second } delay(1000); }
