Types of Robot Wheels Standard Wheels Standard wheels are the most common type of wheels used in robotics projects. They are simple, affordable, and easy to implement. These wheels are typically made of plastic or rubber and have a cylindrical shape with a flat surface that contacts the ground. Standard […]

What are SMD Packages? Surface-mount device (SMD) packages are a type of packaging for electronic components that are designed to be mounted directly onto the surface of a printed circuit board (PCB). SMD packages have largely replaced through-hole mounting in most applications due to their smaller size, lower cost, and […]

Introduction In the world of electrical engineering, potentiometers and rheostats are two essential components that are often used for controlling and adjusting electrical circuits. While both devices serve similar purposes, they have distinct differences in their construction, functionality, and applications. This article aims to provide a comprehensive comparison between potentiometers […]

What is a Bypass Capacitor? A bypass capacitor, also known as a decoupling capacitor, is an electronic component that is used to reduce noise and stabilize the power supply voltage in electronic circuits. It is connected in parallel with the power supply and the ground, close to the device or […]

Introduction to Embedded Computers Embedded computers are specialized computer systems designed to perform specific functions within a larger mechanical or electrical system. Unlike general-purpose computers, such as personal computers or servers, embedded computers are typically dedicated to a single task or a set of related tasks. These systems are found […]

What is a Push-Pull Amplifier? A push-pull amplifier is an electronic circuit that uses two complementary transistors to amplify an input signal. The two transistors are connected in a way that one transistor amplifies the positive half of the input signal while the other amplifies the negative half. The output […]
