BUZZER


General Description:


A buzzer module is an electronic component used to generate sound. It typically consists of a piezoelectric or electromagnetic buzzer, which converts electrical signals into audible tones. The module can operate in either active or passive modes:


1.Active Buzzer: Contains an internal oscillator that generates sound when powered by a DC voltage. It continuously emits a tone without needing an external signal.


2.Passive Buzzer: Lacks an internal oscillator and requires an external signal, such as a square wave from a microcontroller, to produce sound.


Working Principle:


The working principle of the passive buzzer module is based on the piezoelectric effect. When an electrical signal is applied to the buzzer, it causes a piezoelectric crystal inside the buzzer to vibrate at a specific frequency. This vibration produces sound waves that we can hear. The frequency of the sound produced by the buzzer depends on the frequency of the electrical signal applied to it. By changing the frequency of the signal, we can change the pitch of the sound produced by the buzzer.

LED


General Description:


A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.


Working Principle:


LEDs, or Light Emitting Diodes, work based on the principle of electroluminescence. When a voltage is applied to the LED, current flows through the semiconductor material, causing electrons to recombine with electron holes within the device, releasing energy in the form of photons, which produces light.

PUSH BUTTON


General Description:


A push-button, also known simply as a button, is a basic switch mechanism used to regulate aspects of a machine or process. The module is designed for two contacts: when pressed, they are closed and open when released. These buttons are commonly made out of hard material, usually plastic or metal. These switches are widely used in electronic devices, machinery, and control systems for their ease of operation and reliability in initiating commands or processes.


Working Principle:


Push button switches operate through a spring mechanism that compresses and releases internal contacts when the button is pressed. This allows the contacts to touch each other and complete an electrical circuit. Upon release, the spring returns the button to its original position, separating the contacts and breaking the circuit to stop the function.

1. It operates at 5 volts DC.

2. It maintains a low contact resistance of ≤50 million ohms.

RGB LED


General Description:


An RGB LED is a type of light-emitting diode that can emit light in three primary colors: red (R), green (G), and blue (B). By adjusting the intensity of each color component, a wide range of colors can be produced. These LEDs are commonly used in various applications where colorful lighting effects are desired.


Working Principle:


The working principle of an RGB LED involves three separate semiconductor chips within a single package, each emitting red, green, or blue light when current passes through. By varying the intensity of each color using pulse-width modulation (PWM), the LED can create a wide spectrum of colors by mixing these primary colors. For instance, activating only the red light source results in a red glow, while combining red and green produces yellow because these colors mix to form yellow light. This process of mixing different intensities of red, green, and blue light sources enables RGB LEDs to generate a wide range of colors, demonstrating the fundamental principle of color mixing in light.

1. Low Thermal Resistance.

2. No UV rays emitted.

VARIABLE POTENTIOMETER


General Description:


A 10k potentiometer is a type of variable resistor that is used to adjust the resistance in an electrical circuit. The "10k" in the name refers to the resistance of the potentiometer, which is 10,000 ohms (10k ohms). An adjustable potentiometer, 10K Potentiometer Module can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot.


Working Principle:


A 10k potentiometer module operates using a resistive track with a sliding contact (wiper) that adjusts resistance. The wiper's position determines the resistance between the wiper terminal and one of the other terminals. When the wiper is at one end of the track, the resistance between the wiper terminal and that end terminal is maximum (10k ohms), while the resistance between the wiper terminal and the other end terminal is minimum (0 ohms). Conversely, when the wiper is at the opposite end, the resistance values are reversed. Rotating the knob or shaft alters the wiper's position, changing output voltage or current. This versatility suits applications like volume control, light dimming, and motor speed adjustment.


Specifications:


1. It has a resistance of 10 kilohms.

2. Its dimensions are 18 x 23 x 25 mm (length x width x height).
