It captures audio through a MAX9814 microphone amplifier, processes it in real time, and displays the fundamental frequency with a staggering �0.1 cent resolution on a crisp OLED screen. Whether you're tuning a concert guitar, calibrating a laboratory oscillator, or prototyping a commercial tuner, you'll have an instrument that rivals dedicated strobe tuners costing ten times as much.\u003c\/p\u003e\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a self-contained, high-precision musical instrument tuner. The MAX9814 feeds amplified audio into the Due's ADC at 44 kHz, where the YIN autocorrelation algorithm extracts the fundamental pitch. The detected note and cent deviation are rendered instantly on the 0.96-inch OLED. Housed in a custom enclosure, the finished device works with any monophonic instrument - guitar, violin, voice, brass, or wind - and delivers the kind of accuracy normally found only in professional studios.\u003c\/p\u003e\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eImplement the YIN pitch detection algorithm on embedded hardware, from autocorrelation to parabolic interpolation.\u003c\/li\u003e\n  \u003cli\u003eConfigure the Arduino Due's ADC and DMA for stable 44 kHz audio sampling.\u003c\/li\u003e\n  \u003cli\u003eDrive an I2C OLED display with real-time frequency data and cent deviation.\u003c\/li\u003e\n  \u003cli\u003eAssemble, solder, and encase a professional-grade electronic instrument ready for daily use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Due\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMAX9814 Mic Amp\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e0.96in OLED\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
