The higher the sound level, the more LEDs are on. 材料(Materials): 1. Arduino UNO R3 板子 x 1 2. 聲音感測器模組 Sound sensor x 1 3. LED 燈 x 4 4. 杜邦線公對公 male/male jumper wire x 8 5. 220歐姆電阻 220 ohm resistor x 4 6. 麵包板 Breadboard x 1 電路(Circuit): 上圖是用Photentiometer表示聲音感測器模組。 Sound sensor signal pin is wired to Arduino UNO A0. The LEDs' anodes are wired to Arduino UNO pin 3, 5, 6, 9, respectively. 程式碼(The Code): 示範影片(Demo Video): 範例連結(Example Link): https://www.tinkercad.com/things/508wK2VaSjGx
