Reads digital signals from the serial portThis example shows how to monitor the switch status by establishing a serial port communication between the Arduino and the computer.Hardware requirementsArduino Development BoardAn instantaneous switch, button, or mobile Switch10 k

information is sent to the computer for Arduino,RX(r:receive receive) indicates that the Arduino receives The instruction information from the computer, which flashes when the program is downloaded or when it communicates with the computer.Let me illustrate with an example, and we'll write a simple applet that lets the computer display the string "Hello world". And let an LED match, the small lights flashi
