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)
