Introduction: LM3914 Based LED VU METER by Victor Das
LM3914 based LED VU Meter its very simple and effective. Looks great when in action. It runs from 9v to 12v power supply. As like my all other projects its not just a idea or diagram its tested in all ways works just fine. Use 5mm Led looks great you can also use 3mm but the bigger the better. its a mono vu meter if you want stereo than just put two circuits side by side. So build the circuit in good quality PCB and if you face any problem than just gave me a call i am always here to help. Happy building
