Hello, I am new to all this and have been searching for a test for two days and finnaly am posting my question here.
I want to send data to serial pin 11 and revceive this on pin 10 and then print the received data back to my serial monitor running on my laptop connected via USB to my arduino.
So when I remove the jump wire between pin 10 and 11 there will be no data displayed.
Please help me as this is driving me crazzy.
