Toggle and Push Button Difference The difference between a toggle switch and a push button switch is that the toggle switch can remain either high or low, whereas a push button input is momentarily connected when pushed. A spring pushes the button back when you release it. ...
Arduino Logic Control (1): Push button switch to control LED lights.首先打开Arduino IDE，依次选择文件，示例，Digital,DigitallnputPullup。将此程序上传到Arduino开发板上，可以发现在之前的示例中也一直有一个上拉电阻，但是在本次演示中，上拉电阻是不存在的，因为本次演示是通过输入上拉模式。Start by open...
/*ButtonTurns 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 through 220 ohm resistor- pushbutton attached to pin 2 from +5V- 10K resistor attached to pin 2 from ground- ...

1)按键开关(Push Button):当引脚设置为输入(INPUT)模式时,可以识别两种状态:HIGH(高电平)LOW(低电平),引脚为高阻抗状态(100MΩ),此时引脚可用于读取传感器信号或开关信号。 2)按键开关相连不同侧,同侧不相连;上拉电阻:10kΩ;引脚悬空(Floating):引脚设置为INPUT以后,没有外接任何电路,会读取到随机高低电平。
int buttonState = digitalRead(pushButton); 可以看出,HIGH 和 LOW可以存入int变量中。 1-14 数字输入2 - 按键开关控制电路与程序 P15 - 16:27 delay(1)的作用 loop()函数结尾可以加个delay(1);保证程序运行的正确。 1-15 逻辑控制1 P16 - 11:11 if 函数介绍 ...
