Confuse about 8bit long packet data

Projects Programming

HELP!

Can I input a 8bit long packet data into the RX then display it to the serial monitor then after that i will send a 8bit long data into the TX.

If you have samples codes, please post it.

Any help will do. Thank You!

Can I input a 8bit long packet data into the RX

No. The RX pin is read-only.

then display it to the serial monitor

You can display an 8 bit value on the serial monitor, using Serial.print(), Serial.println(), or Serial.write() as appropriate.

then after that i will send a 8bit long data into the TX.

You will already have done that, getting it to the serial monitor.

I mean can the RX read a 8bit long data then display it into the serial monitor, so if the RX and TX won't do the work can I do it to the other pins?

On a standard Arduino UNO the RX/TX pins ARE the serial monitor. You might have to describe what your problem is and not what you think might be a solution.

hi there, can you help us construct the codes for this project pls

Well, they are the hardware serial port that, when the USB cable is connected, the Serial Monitor can connect to.

The Serial Monitor is an application that connects to a serial port.
