Decode byte Help

this is what i'm sending through the serial port

and I am receiving this

Could someone tell me why I receive this?

Most likely you will find that Node-RED's serial node or the serial port it is connected to is not actually listening for data at 9600 bps which is what you've set the Arduino to talk at.

Set the config of your serial port node to "and deliver binary buffers" instead of ascii and see what's coming out then.
