How to Use Arduino & Kit

  1. Install Arduino IDE from the official website.
  2. Connect Arduino board to your computer via USB cable.
  3. Build your circuit using the breadboard and components.
  4. Paste the example code into the IDE.
  5. Click Upload to program your board.

Examples

1. Blink LED

Blink LED wiring 
void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  delay(1000);
}

2. Button-controlled Buzzer

Button wiring 
int buttonPin = 2;
int buzzerPin = 8;

void setup() {
  pinMode(buttonPin, INPUT);
  pinMode(buzzerPin, OUTPUT);
}

void loop() {
  if(digitalRead(buttonPin) == HIGH) {
    digitalWrite(buzzerPin, HIGH);
  } else {
    digitalWrite(buzzerPin, LOW);
  }
}

3. Ultrasonic Distance Sensor + Servo

Ultrasonic wiring 
#include 

Servo myservo;
int trigPin = 9;
int echoPin = 10;

void setup() {
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);
  myservo.attach(6);
  Serial.begin(9600);
}

void loop() {
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
  long duration = pulseIn(echoPin, HIGH);
  int distance = duration * 0.034 / 2;

  Serial.println(distance);
  int pos = map(distance, 0, 200, 0, 180);
  myservo.write(pos);
  delay(500);
}
