Blinking the LED

                void setup() {
                  pinMode(13, OUTPUT);  //Arduino LED
                  pinMode(4, OUTPUT);  //Blue LED
                }
                void loop() {
                   digitalWrite(13,HIGH); //turn on the Arduino LED
                   digitalWrite(4,HIGH); //turn on the Blue LED
                   delay(150);
                   digitalWrite(13,LOW); //turn off the Arduino LED
                   digitalWrite(4,LOW); //turn off the Blue LED
                   delay(150);
                }

Sounding the Buzzer

                    int I;
                    void setup() {
                       pinMode(6, OUTPUT);  //Buzzer

                       //beep once
                       for (I = 0; I < 2000; I++) {
                          digitalWrite(6,HIGH); //turn on the Blue LED
                          delayMicroseconds(250);
                          digitalWrite(6,LOW); //turn off the Arduino LED
                          delayMicroseconds(250);      
                       }
                    }
                    void loop() {
                    }

Making a shooting sound

                    int I;
                    void setup() {
                       pinMode(6, OUTPUT);  //Buzzer

                       //Shooting sound?
                       for (I = 150; I < 400; I++) {
                          digitalWrite(6,HIGH); //turn on the Blue LED
                          delayMicroseconds(I);
                          digitalWrite(6,LOW); //turn off the Arduino LED
                          delayMicroseconds(I);      
                       }
                    }
                    void loop() {
                    }

Using the RGB

When using the RGB, include the Adafruit NeoPixel library in your code
Example:

                #include <Adafruit_NeoPixel.h>
                #define PIN 8
                Adafruit_NeoPixel pixels = Adafruit_NeoPixel(1, PIN, NEO_GRB + NEO_KHZ800);

                #define RGB_Display(R,G,B) \
                  pixels.setPixelColor(0, pixels.Color(R,G,B)); \
                  pixels.show();

                void setup()
                {
                  pixels.begin();
                  pixels.show(); // Initialize all pixels to 'off'

                  RGB_Display(100,0,0); //Red
                  delay(250);
                  RGB_Display(0,150,0); //Green
                  delay(250);
                  RGB_Display(0,0,80); //Blue
                  delay(250);
                  RGB_Display(0,0,0); //Turn the RGB off
                }
                void loop() {
                }

Getting input from the push button

            void setup()
            {
              pinMode(7, INPUT); //push button
              Serial.begin(9600);   
            }
            void loop() {
              if ( digitalRead(7) == 0)
              {
                Serial.println(“Button Pressed.”);

                while (digitalRead(7) == 0) { 
                  //wait for the user to release the push button
                }
              }
            }

Using the IR LED

When using the IR LED, include the IRLib library into your code.

            #include <IRLib>      
            IRsend My_Sender;
            
            void setup()
            {
              pinMode(7, INPUT); //push button 
              pinMode(13, OUTPUT); //LED
              Serial.begin(9600);
            }

            void loop() { 
              if ( digitalRead(7) == 0)
              {
                digitalWrite(13, HIGH);
                My_Sender.send(NEC,97, 8);
                delay(150);
                digitalWrite(13, LOW);
                while (digitalRead(7) == 0) {
                  //wait for the user to release the push button
                }
                delay(100);
              }  
            }

Serial Communication – Getting data

            int RxData;
            void loop() {
              RxData = Serial.read() ;
              if (RxData != -1) { //not equal to 
                if (RxData == 97) { //”a”
                  //turn on LED
                  digitalWrite(13, HIGH);
                }
                if (RxData == 98) { //”b”
                  //turn off LED
                  digitalWrite(13, LOW);
                }
              }
