In this article, we will walk through setting up a simple project on the STM32F446RE Nucleo-64 board where a user button press toggles an onboard LED. The focus will be on manual HAL configuration without relying on interrupts, using a pure polling method. This exercise covers basic GPIO initialization, clock setup, and handling a simple
When you’re getting started with STM32 microcontrollers, one of the best ways to dive in is by building a simple LED Blinky project. In this post, I’ll walk you through every step to create a new STM32CubeIDE project for the Nucleo-F446RE board, manually write the initialization code using STM32 HAL APIs, and explain some important
In this post, I will explain how to connect a PIC18F45Q10 microcontroller to a PC terminal using a PL2303 USB to TTL converter.The idea is simple: blink an LED to confirm the microcontroller is running, and print “Hello World” continuously over UART to the terminal. Along the way, I also faced a few practical issues,
Writing clean, maintainable code is as much about good documentation as it is about writing functional logic. In C programming, comments and input/output (I/O) operations play a vital role in creating programs that are not only efficient but also easy to understand and modify. In this comprehensive guide, we’ll delve into how to use comments
Command line arguments are an essential feature in C that allow programs to receive input directly from the user when they are executed. Building on our previous discussion about the anatomy of a C program and the role of the main() function, this post explores how to harness command line arguments using the parameters argc
C is a timeless language known for its efficiency and its close-to-the-metal approach to programming. Whether you are a beginner or an experienced developer, understanding the anatomy of a C program is crucial to writing effective, maintainable, and well-structured code. In this comprehensive guide, we’ll explore the building blocks that form every C program—from preprocessor

This beginner-friendly course is designed for students and aspiring programmers who want to learn C programming by doing. Instead of long lectures and dry theory, you’ll write real code from Day 1. Every lesson is hands-on, built with short instructions, real examples, and instant challenges — just like how you’d learn in a coding bootcamp
