Description:This is a simple ON/OFF switch for the LilyPad. When the switch is in the ON position it is closed and when it is in the OFF position it is open. Use it to trigger behavior in your programmed project, or to turn LEDs, buzzers, and motors on and off in simple circuits....

DigitalReadSerial- read a switch, print the state out to the Serial Monitor Blink- turn an LED on and off Button State Change- counting the number of button pushes 3、后记 (1)fritzing 电路接线图 今天用 fritzing 绘制的图,上篇多了一个 LED。
项目实战:C#上位机+arduino下位机+控制点亮LED灯 当前比较流行的arduino开发,联动做一个Demo。上位机:C#上位机通过串口发送接收控制协议,来控制下位机;下位机:arduino下位机主控,接受上位机串口协议控制GPIO硬件引脚;硬件电路:面包板LED串220R电路,以arduino引脚驱动; C# adruino Led 软硬开发 下位机 电脑实时控...
