If you’re looking for a beginner-friendly way to get into sensing the physical world with Arduino, ultrasonic distance measurement is a fantastic place to start. In this project, we’ll use an HC-SR04 ultrasonic sensor to measure how far away an…
If you’ve already built a basic servo project and you’re ready for the next step, this one’s for you. In this project, we’re going to control two servo motors using two potentiometers, and on top of that, we’ll display their…
Have you ever wanted to move something smoothly with your hand and see it come to life using a servo motor? Whether you’re building a robotic arm, a remote-controlled car, or just exploring electronics, learning how to control a servo…
Potentiometers — commonly known as “pots” — are essential building blocks in modern electronics and electrical engineering. These adaptable components serve as a bridge between electrical signals and the physical controls we interact with, enabling smooth adjustments of voltage, current,…
Introduction to Brushed DC Motors Brushed DC motors are one of the most fundamental and widely used types of electric motors in the world. Their simplicity, low cost, and straightforward operation make them a favorite in everything from toys and…
What is a DC Motor? A DC motor is a type of electric motor that operates using direct current (DC) as its power source to generate mechanical force or motion. The most commonly used DC motors function by utilizing magnetic…
Motors are the hidden powerhouse behind much of the movement we encounter in our daily lives — from the buzz of a mobile phone to the precision motion of robotic arms and 3D printers. In the world of DIY electronics,…
Infrared (IR) remote controls are everywhere these days — you’ve probably used them to control your TV, speaker system, air conditioner, fan, or even to switch a light on and off. But here’s the cool part: you can also use…
Signals form the basis of communication in electronic systems, allowing devices to transmit and process information. Broadly, signals can be classified into two fundamental types: analog signals and digital signals. In this comprehensive guide, we’ll dive deep into the specifics,…
Digital signals are binary — they can only be either 0 or 1. Analog signals, however, have a continuous range of values and are not limited to just two states. Both types of signals are found in electronic systems, but…
