Summary of MICROCONTROLLER CONTROLLED VU METER CIRCUIT
The article discusses a microcontroller-controlled VU meter circuit using the PIC16F88 microcontroller. It highlights the use of integrated circuits like KA2281 and LM3914 to drive LED displays showing audio levels. The design supports stereo (2×16 LEDs = 32 LEDs) or mono (16 LEDs) configurations, with up to 40 LEDs possible, providing visually appealing dot or bar display modes. The project includes practical PCB schematics created with Eagle, along with hex codes and assembly files for testing, offering a relatively simple yet versatile VU meter solution.
Parts used in the Microcontroller Controlled VU Meter Circuit:
- PIC16F88 microcontroller
- KA2281 integrated circuit
- LM3914 integrated circuit
- LEDs (up to 40)
