Arduino Programming Tutorial

In this tutorial, we'll cover the basics of Arduino programming, focusing on variable types , functions , function return types , and constant declarations . We will use simple examples to demonstrate how each concept works. 1. Variables in Arduino Variables are used to store data that your Arduino program can use. There are different types of variables based on the data they store. Common variable types: int : Stores integer values (whole numbers). float : Stores decimal numbers. char : Stores a single character. boolean : Stores true or false . String : Stores a sequence of characters (text). Example: int ledPin = 13 ; // Integer variable to store LED pin number float sensorValue = 0.0 ; // Float variable to store sensor value char myChar = 'A' ; // Char variable to store a character boolean isOn = true ; // Boolean variable to store true/false String myText = "Hello" ; // String variable to store a string 2. Constants Constants a

BJT vs. MOSFET: Understanding the Key Differences

  When it comes to semiconductor devices, BJT (Bipolar Junction Transistor) and MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) are two of the most commonly used transistors. They both play a critical role in amplifying or switching electronic signals, but their underlying principles and applications are quite different. In this post, we’ll explore the fundamental differences between BJT and MOSFET to help you understand their unique features and decide which one to use in your project. What is a BJT? A Bipolar Junction Transistor (BJT) is a current-controlled device that has three terminals: Collector (C) , Base (B) , and Emitter (E) . BJTs can be either NPN or PNP types, depending on the arrangement of their semiconductor layers. BJTs work by using a small current at the base to control a larger current flowing between the collector and emitter. How BJT Works: Current-Controlled : In a BJT, the amount of current that flows from the collector to the emitter is controll

Getting Started with Arduino Programming: A Beginner's Guide

Arduino programming is an exciting entry point into the world of electronics and coding. Whether you want to build robots, automate tasks, or create innovative gadgets, Arduino makes it accessible to beginners and enthusiasts alike. In this guide, we'll walk you through the basics to help you start your Arduino programming journey. What is Arduino? Arduino is an open-source electronics platform that allows you to create interactive projects. It consists of both hardware (the Arduino board) and software (the Arduino IDE) for writing code. The most popular Arduino board is the Arduino Uno, but there are many others, like the Nano and Mega, tailored for different needs. 1. Gather the Essentials Before diving into programming, you’ll need: Arduino Board: You can choose an Arduino Uno, Mega, or Nano based on your project. USB Cable: For connecting your board to the computer. Breadboard & Jumper Wires: To test circuits easily. Electronic Components: Such as LEDs, resistors, sensors,
