delay(ms):延迟一段时间 :延迟的时长,单位是毫秒 Arduino库函数使用了Timer0的中断,因此不要在任何中断服务程序中调用它,否则程序可能无法正常工作。 Arduino可以执行其他程序,这需要借助第三方库MsTimer2;你可以在http://playground.arduino.cc/Main/MsTimer2下载到它,把下载到的MsTimer2.zip解压到Arduino IDE安装...
In the program below, the very first thing that you do will in the setup function is to begin serial communications, at 9600 bits of data per second, between your board and your computer with the line: 在下面的程序中,在设置函数里第一个要做的事情就会开启串口通信,以 9600 bps,使用下面的代...

Here you can find out how Arduino shiftIn works and how fast it is. The main use for the function to receive serial input from a parallel to serial chip e.g. 74HC165 (8 bits). This allows you to increase the number of inputs to the processor using only two processor pins (you can...

This means that if you have any serial output commands (Serial.print or Serial.println) in your setup() function, you won’t see it in the Serial Monitor because you can’t open the Serial Monitor quickly enough. (You could put a delay in your setup function, but there is another way...

ongoing activity, interrupts in particular, this software serial adapter supports full duplex receive and send. At high bitrates (115200bps) send bit timing can be improved at the expense of blocking concurrent full duplex receives, with theEspSoftwareSerial::UART::enableIntTx(false)function call....
