Hnub no peb yuav ua kom muaj 32 qhab LED Suab Suab Suab Spectrum Analyzer hauv Tsev siv Arduino, nws tuaj yeem qhia pom ntau zaus thiab ua si muisc tib lub sijhawm.

Nco tseg

Qhov siab tshaj plaws 7219LED yuav tsum txuas nrog ua ntej ntawm 100k resistor, txwv tsis pub lub suab nrov ntawm tus hais lus yuav siab heev.

Kauj Ruam 1: Cheeb Tsam

Cov hauv qab no tau siv hauv txoj haujlwm no:

Arduino Nano, Ob 100K resistors, Peb 4.7K resistors, Ob 104 capacitances (104 = 100000pF = 100nF = 0.10μF), 4 hauv 1 Max7219 dot matrix coj, PJ-320D 3.5MM lub qhov (socket), Jumper xov hlau, Breadboard, 3W PAM8403 Class D Suab Amplifier thiab Ob tus neeg hais lus, Tus qauv ntawm Arduino IDE siv yog 1.8.12
