■ JLCPCB Prototype for $2(Any Color): jlcpcb.com
Hi! this Vu-Meter works with only one LM3915, the 20 Led are connected to the IC in order to create a Mirror Effect. The Vu-Meter must be connected to the amplified outputs of the amplifier (High Level Signal). This PCB was designed with Sprint Layout 6 and made with the service offered by JLCPCB at a very low cost! With JLCPCB you can buy 5 PCBs for just 2$!!!
I love Vu-Meters, especially I love building circuits with many LEDs :)
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$ !!!
