本文要用硬體直接控制 LED 燈的亮度，順便了解一些Arduino板子上的腳位。注意：當可變電阻的電阻值太小時，LED有可能會燒掉。
This tutorial will teach how to use UNO to control a LED lightness without coding. Note: the LED might be broken when the resistor value is to too small.
所用到的材料有(Materials)：
1. Arduino UNO 主板 x 1
2. LED燈 x 1 (顏色不拘 the color you like)
3. B10K 可變電阻 10k Potentiometer x 1
4. 杜邦線公對公 male to male wire x 2
5. 麵包板 breadboard x 1
6. 9V電池與9V電池扣或 USB Cable，供電用 9v battery and 9v clip, or USB cable for UNO
根據下面的電路圖將電路接好(The circuit)
注意LED燈的短腳要接在GND。The short leg(cathode) is connected to the GND.
完成圖如下(The completed circuit)：
思考如何接線才能控制多顆LED燈的亮度。
Exercise: how do we control multiple LEDs?
