voidloop(){//需要循环执行的代码} setup():setup()函数只运行一次,用来启动Arduino控制器,将运行中不改变的数值和属性固化到芯片中。The setup function runs once when you press reset or power the board. loop() : loop()函数循环执行,直到按下reset键或者移除电源。 2、Blink.ino中用到的几个函数: ①...
3和2。但是不知道该怎么做 搞名字最烦了 闻名一方 11 并联在4,5上。i2c可以并联使用,地址不同 不可爱的花卷 默默无闻 1 如果你的程序是IIC通信,可以都连接,地址不。改成其他接口没有用的。硬件IIC 天狼落星 远近闻名10 接一块行了,调用的使用不同的地址 爱天天飞翔 ...
LED_BUILTIN：是一个宏，全称：LED-BUILT-IN，内嵌LED的意思，在Arduino的核心库文件“pins_arduino.h”中已经定义，它代表13，一般为了板子兼容写法就这么写，如果写2或者其他引脚数值可能程序代码的移植性没那么好，所以推荐：LED_BUILTINpins_arduino.sh 位置：Arduino_Setup_Home\hardware\arduino\avr...
I/O- All 54 digital bins on the Arduino 2560 can either be used as an input or an output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts and each pin can provide and receive a maximum of 40 mA and has an internal...
Use the Arduino internal pull up resistor. The behavior will be the same as for option no 2. There is no better or worse choice, it depends on the available hardware components you have and some requirements specific to your project. Also it’s a matter of preference: do you want the ...
The STATE pin on the HC-05 zs050 board is connected to the LED 2 pin on the small bluetooth module and the LED 2 pin is used to indicate when there is an active connection. This means the Arduino can connect to the STATE pin and determine when we have a connection. The STATE pin ...
