The application uses ultrasonic sensor to measure distance. And the light bulb's brightness is becoming higher when the distance is getting farther. 材料(Materials)： 1. Arduino UNO R3 板子 x 1 2. 距離感測器模組 Ultrasonic x 1 3. 燈泡 light bulb x 1 4. 杜邦線 jumper wire x 5 電路(Circuit)： 程式碼(The Code)： 示範影片(Demo Video)： 範例連結(Example Link)： https://www.tinkercad.com/things/0wvwVcvzDrx
