Step 1: Assembly

Step 1: Attach Arduino Nano to one breadboard making sure the side with the pins goes all the way into the breadboard.

Step 2: Assembly

Attach a second breadboard to the first one (Note the picture does not include the Arduino Nano connected in step one).

Step 3: Assembly

Step 3: Attach the OLED screen to the second breadboard making sure that the pin side is fully pushed down but do not push too hard as you do not want to break the screen (You can put connect the screen to the breadboard before or after connecting the two breadboards together the picture shows it connected before connecting the breadboards).

Step 4: Wiring

Follow the diagram below to properly wire the screen to the Arduino Nano

Wiring: (Using Jumper Wires)

If your bread board is set up as ours, then you should be able to follow the following instructions word for word. Please refer to the diagrams when following the instructions.

The coloring of the wires does not matter.

1. Connect G3 on board 2 to H4 on board 1

2. Connect H4 on board 2 to H6 on board 1

3. Connect G5 on board 2 to H9 on board 1

4. Connect H6 on board 2 to I10 on board 1

5. Connect I14 on board 2 to J6 on board 1

6. Connect H15 on board 2 to J10 on board 1

7. Connect I16 on board 2 to J9 on board 1

8. Connect H17 on board 2 to B6 on board 1

Double check the wiring before plugging the Arduino into the computer and make any adjustments while the Arduino is unplugged.

Step 5: Code Libraries
