/*Button Turns on and off a light emitting diode(LED) connected to digital pin 13, when pressing a pushbutton attached to pin 2. The circuit: * LED attached from pin 13 to ground * pushbutton attached to pin 2 from +5V * 10K resistor attached to pin 2 from ground ...
This example shows how to detect when a button or button changes from off to on and on to off. 本示例说明如何检测按钮或按钮从关闭变为打开,然后从打开变为关闭。 The circuit: * pushbutton attached to pin 2 from +5V * 10K resistor attached to pin 2 from ground ...
