Circuit & Connections

STEP A: (Connecting LED)

As we are basically building a siren, red and blue flashes look cool. So take 5 red and 5 blue LEDs. Now, connect the negative terminal of these LEDs with a 220 ohm resistor (current limiting) to the negative rail of the breadboard as shown in the circuit diagram. Positive ends of red LEDs are connected to pin 3 to pin 7, while the positive ends of blue LEDs are connected to pin 8 to pin 12 of Arduino's digital pin.

STEP B: (Connecting Piezo Buzzer)

Now, it's time to connect our buzzer and the pushButton to the breadboard. Connect the Piezo buzzer with a 100 ohm resistor to the negative rail and positive end of buzzer connected to pin 13.

STEP C: (Connecting pushButton)

Connect one out of four pins of pushButton with pin 2 and connect down it to GND rail using a pull down resistor of 10k ohm. Connect 5V with another button pin as shown in the circuit diagram.
