 Basic Electronic components


1.LED(Light Emitting Diode)

Pins: LEDs have two pins, a longer positive pin and a shorter negative pin. The positive pin is called the anode and the negative pin is called the cathode.

Connection: To use an LED, it needs to be connected to a power source in the correct direction. The anode should be connected to the positive (+) side of the power source,and the cathode should be connected to the negative (-) side of the power source.

Operating voltage: LEDs typically operate at a low voltage, usually around 1.5 to 3 volts. This means they can be powered by a small battery or a low voltage power supply.

 

Brightness: The brightness of an LED is determined by the amount of current flowing through it. The more current, the brighter the LED will be. However, too much current can damage the LED.

Color: LEDs come in many different colors, including red, green, blue, yellow, and white. The color of the LED is determined by the materials used to make it.

 

2.Bread board:

 

What is a breadboard?

A breadboard is a rectangular plastic board with a bunch of tiny holes in it. These holes let you easily insert electronic components to prototype (meaning to build and test an early version of) an electronic circuit, like this one with a battery, switch, resistor, and an LED (light-emitting diode).The connections are not permanent, so it is easy to remove a component if you make a mistake, or just start over and do a new project.

In Tinkercad circuits, batteries are available with 1.5V, 9V. The battery is labeled with its voltage (V). The voltage indicates the pressure from the electronic circuit power source.

3.Servo Motor:

A servo motor is a type of rotary actuator that provides precise control of angular position, velocity, and acceleration. It typically consists of a DC motor, a feedback sensor, and a control circuit. Servos are used in applications requiring precise control, such as in robotics and remote-control vehicles.

 

4.DC Motor:

A DC motor converts direct current electrical energy into mechanical energy. It is commonly used in various applications where simple, adjustable speed and torque control are needed. DC motors are found in everything from small gadgets to large industrial machines.

5.Vibration Motor:

A vibration motor is a type of motor specifically designed to create vibrations. It typically includes an unbalanced weight attached to the shaft, which causes the motor to vibrate as it spins. These motors are often used in applications like mobile phones (for haptic feedback) and gaming controllers.

6.Hobby Gear Motor: 

A hobby gear motor combines a DC motor with a gear train. The gear train reduces the motor's speed while increasing its torque, making it suitable for applications in hobbyist projects and remote-controlled vehicles. These motors are popular in DIY electronics and small-scale robotics due to their versatility and ease of use.

7.Transistor:

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It has three terminals: the base, collector, and emitter. The transistor can act as a switch or an amplifier, controlling a large current with a small input current.

8.Diode:

A diode is a semiconductor device that allows current to flow in one direction only. It has two terminals: anode (positive) and cathode (negative). Diodes are commonly used for rectification, converting AC (alternating current) to DC (direct current).

9.Tri-Color LED:

A tri-color LED is a light-emitting diode that can emit three different colors (usually red, green, and blue). It typically has four pins: one common pin (either anode or cathode) and three other pins corresponding to each color. By adjusting the current to each pin, you can mix the colors to produce a wide range of colors.

10.Multimeter:

A multimeter is a versatile instrument used to measure electrical properties such as voltage, current, and resistance. It can be used in various modes to test circuits, diagnose faults, and measure different electrical parameters.

11.Buzzer:

A buzzer is an audio signaling device that produces sound in response to an electrical signal. It is commonly used in alarms, timers, and other devices where an audible signal is required. Buzzers can be mechanical, electromechanical, or piezoelectric.These components are essential in various electronic circuits and applications, each serving a unique purpose.

12.Micro-bit:

The microbit is a small, programmable microcontroller designed for educational purposes, particularly to introduce coding and electronics to beginners. It has a variety of built-in features:

LED Matrix: A 5x5 grid of LEDs that can display patterns, text, or images.

Buttons: Two programmable buttons (A and B) for user input.

Sensors: Includes an accelerometer to detect movement, a compass for direction, and a temperature sensor.

Connectivity: Supports Bluetooth and can communicate with other devices.

Input/Output Pins: Allows connection to external components like sensors, motors, or LEDs.
