Webduino 模擬器：按鈕控制LED亮滅 (Webduino Simulator: Control a LED with a Button)

這次換用 Webduino 模擬器上的按鈕來控制 LED 燈。
This tutorial will control a LED with a button.

模擬器的接線方式，為一顆 LED ，長腳接D13，短腳接GND。(注意：實際硬體的LED燈是需要接上電組的，不然LED燈有可能會燒掉。)以及一個按鈕，S接D10，V接5V，G接GND。

Wiring:

1. LED anode → UNO D13
2. LED cathode → UNO GND
3. Button S(signal) → UNO D10
4. Button V(voltage) → UNO 5V
5. Button G(ground) → UNO GND

The circuit design is the following diagram. (Note: a resistor is needed for physical wiring to avoid destroying a LED.)
