● 连接导线 Arduino连接干簧管的电路图 使用Arduino连接干簧管(Reed Switch)的工作过程 Arduino Uno开发板是一款基于ATmega328p微控制器的开源电路板。它有14个数字引脚(其中6个引脚可用作PWM输出)、6个模拟输入以及板载稳压器等。Arduino Uno具有32KB闪存、2KB SRAM和1KB EEPROM。它的工作频率为16MHz。 Arduino Uno...
Serial.println("Switch opened"); digitalWrite(LED_PIN, LOW);// Turn the LED off} } 上传草图后,抓住磁铁,把它靠近开关。当磁铁到达干簧管1厘米的距离时,它应该触发。 代码说明 该代码比较通俗易懂。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;co...
To read the Reed-switch and light the LED accordingly: const int ReedPin = 4; const int ledPin = 2; void setup() { pinMode(ledPin, OUTPUT); pinMode(ReedPin, INPUT_PULLUP); } void loop() { digitalWrite(ledPin, digitalRead(ReedPin)); } ...
