Hardware wiring - TX/RX not clear #4

Hi,

You wrote: "Then connect Arduino/ESP(you need a power converter from 5V to 3.3V for ESP) and Display to power and ground. Then connect serial line to RX pin of Arduino/ESP and using a resistor (for best work a diode) to TX."

So I connect the RX directly to the TR bus, but it's not clear to me how is the wiring to the TX of the Arduino.

Tnx.
