LM3915 BarGraph Stereo Vu Meter ( 30dB / 20 LED ) - PCB Tutorial
■ JLCPCB Prototype for $2(Any Color): https://jlcpcb.com
Today I build this Vu-Meter ( 30dB Range Stereo / 20 LED ) using
Bar Graphs, some fantastic LED modules. This circuit works with LM3915 and LM3916.. also works with LM3914 but these are not recommended for Audio applications.
Difference between LM3914/15/16: https://youtu.be/7avb905F-MQ
After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!

*Don't use my PCB for profit or sponsored videos.
This circuit must be powered with 9V DC, below I leave the references to view: the electronic circuit diagram, the PCB and the Gerber file to be uploaded directly on the JLCPCB website.
*You can see the complete procedure to upload the Gerber file on jlcpcb.com in the video from 1:07
**JLCPCB have a Technical Support for exporting Gerber files from many software at this link: https://support.jlcpcb.com/category/23-technical-support
For any other questions you can ask me for explanations in the video comments:)
