Buzzer is used to generate sound, beep or even melody of a song. It can be found in alarm devices, computers, timers and confirmation of user input such as a mouse click or keystroke. A piezo buzzer is not like a regular speaker that you might think of. It uses a material that actually changes shape when you apply electricity to it which in turn creates noise. The faster you bend the material, the higher the pitch of the noise that is produced.

A servo motor is a type of motor that is designed to provide precise control of position and speed. It is a rotary actuator that can rotate to a specified angle with a high degree of accuracy. Servo motors are commonly used in a wide variety of applications, including robotics, factory automation, camera stabilization systems, and remote-controlled vehicles, to name a few.

Pulse Width Modulation (PWM) is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between ON and OFF. If you repeat this on/off pattern fast enough with a LED for example, the result is as if the signal is a steady voltage between 0 and VCC controlling the brightness of the LED.

The KY-016 is capable of producing wide range of different colors by mixing blue, green and red lights. The RGB LED module will not require any limiting resistors. Those resistors are already integrated in the circuit, and so 5V can be directly used as power input.

A piezo buzzer is a small device that converts electrical signals into sound waves. Unlike traditional speakers, piezo buzzers operate on the piezoelectric effect. When a voltage is applied, the buzzer's piezoelectric crystal deforms, producing sound waves. This simplicity makes piezo buzzers cost-effective, lightweight, and ideal for applications where the space is limited.

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language and the Arduino Software (IDE).

Home Alone has since been considered one of the best Christmas films and Somewhere in My Memory has been nominated as best original song. We wanted to recreate the melody of the film's theme song with a piezo buzzer and share with you. Buzzer is used to generate sound, beep or even melody of a song. It can be found in alarm devices, computers, timers and confirmation of user input such as a mouse click or keystroke.
