Push Button with Buzzer

Components (Things You will need)

Building the circuit

Things Needed:

• Arduino Uno = 1
• Arduino USB cable = 1
• Buzzer = 1
• Red jumper wires = 2
• White jumper wire= 1
• Green jumper wire= 1

Mounting the component on the breadboard

Step 1: Push Button:Insert two pins into row g and two pins into row d on the breadboard

step 2: Buzzer: Insert the buzzer into row J on the breadboard. Ensure the longer pin (positive) is correctly aligned.

Note:Take note of where each of the pins are placed on the bread board

WIRING THE CIRCUIT¶

Things Needed:¶

• Red jumper wires = 2
• White jumper wire= 1
• Green jumper wire= 1

step 1: Red Wire: Connect one end to the pin on the breadboard and the other end to Digital Pin 2 on the Arduino Uno.

step 2: White Wire: Connect one end to the other pin on row d and the other end to GND on the Arduino Uno

step 3: Red Wire: Connect the positive pin of the buzzer to Digital Pin 3 on the Arduino Uno.

step 4: Green Wire: Connect the negative pin of the buzzer to GND on the Arduino Uno

PROGRAMMING

Step 1: Open your Arduino IDE. 

Step 2: Type the following codes before the void setup function.

Step 3: typeint B = 3;as shown in the picture below.

Step 4: Type int buttonState= 0; as shown in the picture below.

Step 5: After the void setup ()within the curly brackets type the following codes.

pinMode (ButtonPin, INTPUT_PULLUP);
pinMode (B, OUTPUT);

Step 6: : After the (void loop ()) within the curly brackets type

buttonState = digitalRead(ButtonPin);

 if (buttonState == LOW) {
digitalWrite (B, HIGH);
delay (500);
digitalWrite (B, LOW);
}
