Each of the 14 digital pins on the Uno can be used as an input or output, using pinMode(),digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor (disconnected by...

按下按钮时,将其拉到地面。 pinMode(2, INPUT_PULLUP);pinMode(3, INPUT_PULLUP);pinMode(4, INPUT_PULLUP);pinMode(5, INPUT_PULLUP); 下面的代码块用于在按下按钮时播放歌曲。它读取每个按钮的数字值,当它变低(零)时,它假设按钮被按下并通过调用所需的函数播放相应的音调。 if(digitalRead(2)==0...
If you are using Arduino Mini Pro, UNO or similar, pay attention to the pin 13 and the use of an internal pull-up resistor. This pin has a LED and a resistor connected on the board. When this pin is set to HIGH, the LED comes on. If you use the internal pull-up resistor of ...
An Arduino core for ATmega8535, ATmega16, ATmega32, ATmega164, ATmega324, ATmega644 and ATmega1284, all running theUrbootbootloader. Most Arduino UNO-compatible libraries will work with this core. If not, it's fairly straightforward toport a library. This core requires at least Arduino IDE v1....
Arduino UNO R3开发板 注意,在Arduino环境下开发时,一定要善用串口监视器,这是一个好东西。 相关资源链接: 火花空间 http://www.oursparkspace.cn/ Arduino官网 https://www.arduino.cc/ 开源软件托管平台 https://github.com/ 另外,大家必须习惯于自己解决问题,习惯于利用搜索引擎去寻找问题的答案。
打开一个?电压读取串口 其实有大量注释,就是你别看见英文就头秃 配置段初始化了一个串口,指定了baud 然后用函数读取A0这个引脚,赋值给senorValue 接着打印出来,用了一个延时.为了稳定读取 代码语言:javascript 复制 voidsetup(){// initialize serial communication at 9600 bits per second:Serial.begin(9600);}...
