LM3915 BarGraph Stereo Vu Meter ( 30dB / 20 LED ) - PCB Tutorial

Описание: ■ JLCPCB Prototype for $2(Any Color): https://jlcpcb.com

Today I build this Vu-Meter ( 30dB Range Stereo / 20 LED ) using
Bar Graphs, some fantastic LED modules. This circuit works with LM3915 and LM3916.. also works with LM3914 but these are not recommended for Audio applications.

Difference between LM3914/15/16:    • LM3914 vs LM3915 vs LM3916 - What are the ...  

After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!
