Turning a Raspberry Pi Zero 2 W Into a NAS Using a 1TB External HDD

Most people think you need a dedicated NAS device from Synology or QNAP to create network storage at home. While those systems are excellent, they are also relatively expensive if your goal is simply storing files, backups, documents, photos, or project data across devices. What many people don’t realize is that a tiny Raspberry Pi

Embedded C Programming

Updated: March 15, 2026
Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
