Relay Basics

Relays are indispensable in electrical engineering, but among their many types, the Electro-Mechanical Relay (EMR) remains the most iconic and widely used

Arduino Digital Input

we will explore how to configure digital pin 7 as an input, read its state, and display the result on the Serial Monitor.

Ohm's Law

Ohm’s Law states that the current through a conductor is directly proportional to the voltage across it.

Python: Getting Started with Basics

Python is a beginner‑friendly programming language known for its simplicity and readability. It lets you start coding quickly with clear syntax, making it ideal for learning and building projects.

Python: Data Structures Basics

Python data structures organize and store data efficiently for easy access and manipulation. Common ones include lists, tuples, sets, and dictionaries, each serving unique purposes in programming.

Arduino: Getting Started - A Beginner’s Introduction

Arduino is an open‑source platform that makes it easy to build electronics projects with simple coding. Getting started involves connecting the board to your computer, installing the Arduino IDE, and uploading your first sketch.

What is a Resistor?

A resistor is an electronic component that limits or controls the flow of electric current in a circuit. Its resistance value, measured in ohms (Ω), helps manage voltage and protect other components.

Voltage Divider

A voltage divider is a simple circuit that reduces voltage using two resistors in series. The output voltage is a fraction of the input, determined by the resistor ratio.
