This is a Vu-Meter with 20 LEDs, driven by two LM3915, the circuit has been professionally realized on a PCB (Printed Circuit Board) by the JLCPCB service. In this video I will go to assemble this Vu-Meter step by step. Assembly begins at 3:40 in the video and at 6:25 you can see the Vu-Meter test with a song.
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.
JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 10 PCB Boards for 2 Dollars.
JLCPCB is the largest PCB prototype enterprise and a High-Tech manufacturer specializing in quick PCB prototype and small batch PCB production. With over 12 years of experience in PCB manufacturing, has more than 400,000 customers, with over 10,000 online orders of PCB a day. Customer service is one of the best in the world, so feel free to upload your Gerber files for file review before completely submitting your order.
