首先定义了两个常量,它们声明了干簧管和内置LED连接到的Arduino引脚。 登录后复制constintREED_PIN =2;constintLED_PIN =13; 在setup()函数中,干簧管引脚配置为输入,而LED引脚配置为输出。干簧管引脚启用了内部上拉电阻。 登录后复制voidsetup() {Serial.begin(9600);pinMode(REED_PIN, INPUT_PULLUP);pinMode...
在代码中,我们必须先定义Reed开关和LED连接到Arduino的引脚。干簧管连接到Arduino的数字引脚4,LED通过限流电阻连接到Arduino的数字引脚7。变量“reed_status”用于保存干簧的状态。 int LED = 7; int reed_switch = 4; int reed_status; 复制代码 在setup()函数中,我们需要设置LED和干簧管连接的引脚状态。引脚4...
ESP.deepSleep(30e6);// Deep sleep mode until RESET pin is connected to a LOW signal (for example pushbutton or magnetic reed switch)//Serial.println("I'm awake, but I'm going into deep sleep mode until RESET pin is connected to a LOW signal");//ESP.deepSleep(0);}voidloop(){ } ...
//ESP.deepSleep(30e6); // Deep sleep mode until RESET pin is connected to a LOW signal (for example pushbutton or magnetic reed switch) Serial.println("I'm awake, but I'm going into deep sleep mode until RESET pin is connected to a LOW signal"); ESP.deepSleep(0); } void loop()...
Reed switch A magnetic reed switch is a switch that change it's state whenever a magnetic field is present. Magnetic reeds are cheap and really easy to find online. They have a lot of practical uses like checking if a window/door is open or not. ...
// Deep sleep mode until RESET pin is connected to a LOW signal (for example pushbutton or magnetic reed switch) //Serial.println("I'm awake, but I'm going into deep sleep mode until RESET pin is connected to a LOW signal"); ...
An example implementation of a web interface for an Arduino Nano 33 IoT using a websocket (AP version with WiFi toggle switch) The Arduino serves as both a web server and a websocket server. The idea is that the Arduino can serve up its own interface for changing settings and showing data...
Sets the Modbus register to represent the switch. This value is the offset (0-based) to be placed in its supervisory or testing software. Note that if your software uses offsets 1-based the set value there should be 101, for this example. ...
but what makes the Arduino microcontroller platform so useful is that the system is equipped with both inputs and outputs. By combining both, your opportunities are nearly limitless. For example, you can use a magnetic reed switch to play music when your door opens, create an electronic lockbo...
