I'm very sorry if I offended you
I will no longer be offended, and you will have nothing to be sorry for, after you have fixed post #2.
Albert94:
Can you kindly take a look at it?
I looked at it and I agree with Steve (slipstick). Your code does not attempt to send any message by flashing the led. It simply flashes the led 5 times. There is no message contained within the flashing. Try to write some code to flash the led in a way which sends your message. If you get stuck, post your best attempt and we will try to help.
My suggestion would be to use the SoftSerial library to send your message to the Arduino pin that your tx circuit is connected to. Same for the receiving Arduino.
