Dot Matrix Emojis and Wording

This project is about showing emojis or wordings on the 8x8 dot matrix. This project could be used for display or decoration, and it could work especially well in dark places as the dot matrix lighting shows better/clearer. My reference link for this project is from https://randomnerdtutorials.com/guide-for-8x8-dot-... I've improved from the reference link by adding more emojis, and wording to the dot matrix [In code]. Therefore, it has more faces, emojis and wordings for display or decoration.

Materials needed are:

[For wiring]

1. 8×8 Dot Matrix with MAX7219

2. Arduino IDE

3. Jumper wires x5

4. USB connectors to Arduino

[For cover]

1. Cardboards x2

2. Scissors

3. Hot glue gun

4. Decoration tape [Optional]

The reference made the dot matrix with 3 different types of emoji faces, thus, I changed and added some coding in this certain project. For example, I've added another type of emoji [Heart shape], and wordings.

1. Prepare all materials needed

2. Use 5 wires to connect to the 8×8 Dot Matrix

- VCC connect to 5v

- GND connect to GND

-DIN connect to D12

- CS connect to D10

- CLK connect D11

3. Type code

4. Connect to computer [Arduino] with USB connector

1. Measure out the length of arduino

2. Cut all 6 pieces according to measurements [Top, sides, Bottom]

3. Measure the length and width of the dot matrix

4. Cut a square/shape that fits the dot matrix on the top piece

5. Cut a small square on one of the side of the arduino [For USB port]

6. Hot glue all the pieces together to form a box-shape

[7. Optional: Use decoration tape to cover the edges of each pieces, for coverage of the hot glue traces]
