@antinkramer: Today’s upgrade: adding a potentiometer to control the volume. A few wires, one analog input, and now the RFID music player has smooth hardware volume control instead of fixed levels. Small feature, but it makes the project feel much more like a real product. Still a lot more to build! 🚀 #arduino #rfid #electronics #DIY #maker
