Serial communications provide an easy and flexible way for your Arduino board to interact with your computer and other devices. This chapter explains how to send and receive information using this capability. Chapter 1 described how to connect the Arduino serial port to your computer to upload sket...

Serial Communication URL Arduino 板卡使用 Serial 与电脑或其它设备进行通讯。所有 Arduino 板卡至少拥有一个串行端口(也称URAT 或USART):Serial。Serial 工作于数字引脚 0 (RX) 和 1 (TX) ,同时也通过 USB 与电脑通讯。因此,如果需要使用 Serial 功能,便不能同时将引脚 0 和 1 用作数字输入和输出。 我们可以...

Preface: Arduino allow use a TX & a RX pin conduct serial communication with Android or Windows,But at many times,If you want to communication with more device,For instance,Use ESP8226 module and HC05 moudule at the same times, You must use software(virtual) serial conduct communication. ...
