Vu-Meter Stereo 30dB Round Shape LM3915 - PCB TUTORIAL

■ JLCPCB Prototype for $2(Any Color): https://jlcpcb.com This is a stereo Vu-Meter with Round Shape The circuit is based on an LM3915, and the PCB was made with JLCPCB. For this PCB I decided to try "Gold Fingers" - on the Pads a small layer of Gold is placed to ensure better conductivity and prevent oxidation. The core of this circuit is the LM3915 a 3dB increments logarithmic display typically used to display audio signal using 10 LED. After trying the excellent service offered by JLCPCB I recommend it, the quality of the circuits is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier.
