Example:
Inthistest,Arduinowillsendstring“Hi,IamArduino!”everysecond.Thosedatawillbe
senttoPCwirelessviathosetwomodules.
Hereisthecode:
voidsetup()
{
//startserialportat9600bps:
Serial.begin(9600);
}
voidloop()
{
delay(1000);
Serial.println("Hi,IamArduino!");

UploadthecodetoArduino.Pleasenote:keepTXandRXdisconnectedwithmdules
whileuploadingcodebecauseuploadingwilluseUART.
Connectthehardwareasfollows:

Pleasenotethatthismoduleshouldbepowered3.3V,not5V.
ConnecttheUSBmoduletoPC.Thenpoweron.
Wetookapictureshownbelow:

ToreceivethestringsentfromArduinotoPC,wecanalsouseArduinoIDE.
StartanewpageinArduinoIDE,andchoosetheserialportofUSBUR24A.Hereinmy
PCisCOM7.
