电子知识普及: VCC表示连接到三极管集电极(C)的电源。 VSS表示连接到场效应管的源极(S)的电源。  通常VCC为电源正,而VSS为电源负或者地。

下图中A点就相当于单片机的I/O口,A点相当于单刀双掷开关,可以接到+5V,也可以接到电源地。接到+5V或者悬空,整个电路中没有电流流过,LED的状态是熄灭。如果A点接到电源地,2端压差5V,假设LED正常工作压降1.5V,正常工作电流10mA。我们通过图上的参数得知实际工作参数:电流I=(5V-1.5V)/390 欧姆=8.9mA,接近于正常工作电流,所以LED 被点亮。在数字电路中,接+5V为电平"1",接地为"0"。

Let's face it: most engineers aren't able to explain what they do to another engineer --"Getting started with arduino" Massimo太搞了,码农们懂得。。。
