8x8 Dot Matrix: Confession and Heart Animation

Introduction:

This Arduino creation serves the purpose under a situation when people are too shy to confess or say some specific wordings. Under the use of this product could display word by word to form a short sentence or confession. Thus with heart animation at the end of the message. This product could be useful and targeted for shy people and wanted a creative way to confess or inform a message to others.

Supplies

For wiring:

Arduino board x1

8×8 Dot Matrix with MAX7219

USB connectors to Arduino

Jumper wires x5

For cover

Cardboards x2

Scissors

Hot glue gun

Decoration tape [Optional]

Tape

Ruler

Step 1: Coding

Please visit this website to copy and see the coding used for this product!

The coding includes the heart animation and some wording ["I like U"]

Step 2: Wiring

Above is a reference picture of the circuit that you could follow for the wiring process!

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

Step 3: Making the Cover - Cardboard Sizes

Specific carboard sizes

18.2cm x 12.4cm - x2 [Top & Bottom]

12.6cm x 5.6cm - x2 [Left & Right]

17.7cm x 5.8cm - x2 [Front & Back]

Step 4: Taping the Arduino Board - Optional

Here is a tip and suggestion while making/gluing the cover!

I suggest using some [clear] tape to secure the Arduino board on the bottom piece of cardboard in case it becomes inconvenient to work with later on during the gluing process.

Step 5: Gluing the Pieces

Here is a picture reference for the gluing layout of the cover

- Remember to cut a small hole for your USB connecter on the left

- Don't glue the top piece [cardboard] yet

Follow the layout and glue the cardboard together securely with hot glue

Step 6: Top Piece of Cover

The top piece of cover should come last to glue on

- Remember to cut a small square for the 8x8 matrix LED to display

- Use tape to tape down both sides of the LED matrix on the cardboard

- Remember to plug in the connector before you seal off the top!

Step 7: Final Product + Decoration Tape [Optional]

The final product/cover should be looking like something from the reference picture

The final step would be to run in the code and the product is then finished

Optional:

Use decoration tape to cover the edges of the cover [As it might seem messy with the hot glue]

Step 8: Video Display
