Summary of MICROCONTROLLER CONTROLLED VU METER CIRCUIT

This article describes a microcontroller-controlled VU meter project using a PIC16F88 to drive LED displays (stereo 2×16 = 32 LEDs or mono 16; up to 40 LEDs possible). It references alternatives like KA2281 and LM3914, provides PCB/Eagle schematics, hex/ASM test code, and a video source; the author offers a simple practical PCB and instructions for building the VU meter.

Parts used in the Microcontroller Controlled VU Meter Circuit:

  • PIC16F88 microcontroller
  • KA2281 integrated circuit (alternative)
  • LM3914 integrated circuit (alternative)
  • LEDs (16, 32, or up to 40, depending on configuration)
  • Printed circuit board (PCB) fabricated from Eagle schematics
  • Resistors (for LED current limiting and signal conditioning)
  • Capacitors (for power decoupling and filtering)
  • Power supply (suitable voltage for PIC and LEDs)
  • Audio input connectors and wiring
  • Programming interface or PIC programmer (to load hex/ASM code)
