Analog Joystick: A Guide to Electronic Components

The analog joystick is a commonly used electronic component in video games. It allows you to control movement and perform various actions by manipulating the joystick. In this article, we will explore the functionality and pins of the analog joystick, as well as provide example code for reading its values. The analog joystick consists of five pins: GND: This pin serves as the input low signal. +5V (or +3.3V for 3....

Electronic Components: Buzzers

Buzzers are electronic components that are used to generate sound. In this blog, we will explore the different types of buzzers and their functionalities. Active Buzzers Active buzzers are a type of buzzer that have additional logic compared to passive buzzers. They require a direct current (DC) connection and are more expensive than passive buzzers. To generate sound with an active buzzer, you need to connect a 0V wire and a signal wire, alternately switching between high and low voltage levels at different frequencies based on the desired sound....

Electronic Components: LEDs

Light Emitting Diodes (LEDs) are essential electronic components for various applications and prototypes. They are easy to use and perfect for exploring different concepts. In this blog post, we will focus on 5mm LEDs commonly used for prototyping. An LED has two leads: the anode and the cathode. The anode is usually longer than the cathode. It is crucial to connect the anode to the positive lead (+) and the cathode to the negative lead (-) correctly to ensure the LED functions properly....

Electronic Components: Resistors

A resistor is an essential electronic component that is designed to impede the flow of electrical current within a circuit. There exists a wide variety of resistors available, constructed using different materials and offering varying levels of resistance. In my collection, I currently possess the following resistors: 10Ω 220Ω 330Ω 1kΩ 2kΩ 5kΩ 10kΩ 100kΩ 1MΩ Each resistor value is distinctly represented by a unique color combination, aiding in easy identification....

Electronic Components: Servo Motors

Servo motors are programmable motors that have the ability to rotate to positions spanning over 180 degrees. These motors are commonly used in various applications that require movement and come in different sizes. For Arduino and battery-powered applications, the micro servo or RC servo is often used. Examples include the SG90 and the MG90S. Both of these servos function in the same manner. A mechanical arm can utilize multiple MG90S servos, as shown in the image below:...

Potentiometers: Understanding and Applications

Potentiometers are essential electronic components that play a crucial role in various circuits. They are small in size and typically feature two connectors on one side and one on the opposite side. The two connectors serve as the input, connected to the negative and positive terminals, while the remaining connector acts as the output. The functionality of a potentiometer lies in its ability to modify resistance. By rotating the potentiometer, a fraction of the voltage difference between the input pins can be obtained at the output pin....

Understanding RGB LEDs: A Guide to Electronic Components

RGB LEDs are a unique type of LED that can display various colors based on their configuration. While traditional LEDs typically emit a single color, RGB LEDs combine red, blue, and green LEDs into one, allowing for a wide range of color options. In addition to the three primary color leads, RGB LEDs also feature a common pin. There are two types of RGB LEDs: common anode and common cathode. It’s essential to understand the type you’re working with as it affects how you build your circuits....
