以下是一个简单的电子式Push锁的代码示例(基于Arduino平台): cpp const int pushButtonPin = 2; // Push锁按钮连接的引脚 int buttonState = 0; // 按钮状态变量 void setup() { pinMode(pushButtonPin, INPUT); // 设置按钮引脚为输入模式 Serial.begin(9600); // 初始化串口通信 } void loop() { ...

From the circuit above, you can connect a push-button to the Arduino board by connecting: One leg of the push-button to 5-volt power supply on the UNO board. The other leg to GND through a pull-down resistor. A digital pin (pin 8 in our circuit) to the other end of the GND leg...

In pull-down resistor mode, when the push button is pressed, input to the GPIO pin will be logic low state and otherwise logic high state. So We will use the digital input pin of the ESP32 development board to read this logic using pinMode() function of Arduino IDE. So now let’s ...
