Simple LED VU Meter

Lets Build This VU Meter

How to make a VU meter. Hello Friends, in this post I make a VU meter using LM3915N-1 IC. You can use this VU meter up to 100W amplifier. You can power up this VU meter with a 12V power supply. Using the 100K preset, you can easily adjust the LED level of this VU meter. Connect this VU meter with your amplifier output and adjust the LED level as per your requirement. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to www.pcbway.com for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay.


You just need to upload the Gerber File, and select the quantity, color, silkscreen, thickness etc. Then select your country, and shipping method and then Pay. PCBWay (www.pcbway.com) will deliver your PCB within 7-10 days.


After one week I received my PCB. You can see the PCB quality, it's awesome. I have ordered Black PCB. But you can choose your PCB color. PCBWay provides a total of 9 color solder mask - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black, and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. And maximum Layer is up to 14 Layers. And If you order PCB the first time at PCBWay, then you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.
