So, the first time you release the button, the LED will turn on. The second time, it will turn off. Etc.The code#define LED_PIN 8 #define BUTTON_PIN 7 byte lastButtonState = LOW; byte ledState = LOW; void setup() { pinMode(LED_PIN, OUTPUT); pinMode(BUTTON_PIN, INPUT); } ...
// put your main code here, to run repeatedly: 将主程序代码放这里,会重复运行: } 2、模拟串口读取 -Bare Minimum code needed This example contains the bare minimum of code you need for a sketch to compile properly on Arduino Software (IDE): thesetup()method and theloop()method. 该例包含...
This code tracks the state of the LED (is it on or off) and then tracks the button to see if it has been pressed. Upon pressing the button, the state of the LED is changed. /* ARDUINO BUTTON TOGGLES LED By: TheGeekPub.com More Arduino Tutorials: https://www.thegeekpub.com/ardui...

Serial.println("LED ON!"); }elseif(val=='f'){ digitalWrite(ledpin,LOW); Serial.println("LED OFF!"); } } 3. 将蓝牙模块的RxD链接到arduino的Tx口上,蓝牙的TxD链接到arduino的Rx口上。 4. 打开android的blueTerm ,链接到蓝牙,默认密码1234。
