You don’t need an expensive piece of hardware to start experimenting with embedded systems. An ESP32, OLED display, rotary encoder, RFID module, and an Altoids case can become the foundation for a surprisingly capable pocket-sized project. The best part is that you control the software. You can build your own menu system, experiment with RFID, create small utilities, and keep adding features as you learn more about ESP32 development. Projects like this are a great way to turn inexpensive electronics into something you actually understand and built yourself. Just make sure you only test RFID and other wireless functionality on devices, tags, and systems you own or have permission to test. #fyp #viral #ESP32 #DIYTech #electronics
