In the previous article, we implemented a button-controlled LED toggle using a polling method. While simple and effective for basic projects, polling is inefficient for real-time or low-power embedded systems. In this article, we will improve the design by configuring the button press to trigger an external interrupt (EXTI) instead of continuously polling the button
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,
This post explains how to drive a common cathode seven-segment display (SSD) with the PIC18F45Q10 microcontroller. We’ll implement a hexadecimal counter (0-F) that cycles through each digit, showcasing how to manipulate output pins to control the display. What is a Seven-Segment Display (SSD)? A Seven-Segment Display (SSD) is an electronic display device widely used for
In this blog post, we’ll explore how to interface a simple LED with the PIC18F45Q10 microcontroller and make it blink at regular intervals. This is a great beginner project to understand how to work with input/output (I/O) pins, configure the microcontroller, and implement a delay for controlling time-based events.

This hands-on, beginner-to-advanced course is designed for students, electronics hobbyists, and engineers who want to learn how to simulate real-world circuits using LTspice.Instead of just theory, you’ll build, test, and analyze circuits inside LTspice, an industry-standard simulation tool used across academia and industry. By the end of this course, you’ll be able to simulate analog,
This beginner-friendly course is designed for students, hobbyists, and aspiring makers who want to learn Arduino programming by building real circuits and writing real code. Just like in a real electronics lab, you’ll connect components, upload sketches, and make things move, blink, and respond. Whether you’re working on your first project, preparing for college lab
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
