2. Now, you'll need to connect the display to Arduino using these jumper wires. The
following image shows a picture of the connection you'll need on the display:
3. The preceding image shows the four pins you need to connect to the display. They
are GND and VCC pins, and RX and TX pins from Arduino. The VCC and GND
will come from the 5 V and GND pins on Arduino. The RX and TX will come
from two pins that you will specify in the code. In this case, looking at the docu-
mentation, the code will use pin 11 as RX and pin 12 as TX. So, to connect your
Arduino to the display, first plug the four-wire connector into the display; then,
use the male-to-male jumpers to connect the four connectors to the proper con-
nections on the board, as shown in the following image:
