Software environment

1. Arduino IDE 1.8.19 at least
2. Boards : https://dl.espressif.com/dl/package_esp32_index.json
3. ESPAsyncWebServer (Mathieu Carbou) 3.3.21
4. FastLED (Daniel Garcia) 3.9.2

Arduino IDE configuration

1. board choice : ESP32C3DEV
2. upload speed : 115200
3. USB CDC on Boot : Enabled (to enable printf for debug)

This step is pretty straightforward. You just need to download all the required libraries and upload the code with the correct configuration. 😊

To mount the LED panels onto the hat:

1. Place each panel between two support brackets and glue the brackets together to secure the panel.
2. Make holes in the hat where the panel cables need to pass through, so you can route them inside.
3. Assemble everything using magnets or glue, depending on your preferred method.

The electrical connections are simple too:

1. Solder the LED connector as shown in the image.
2. Connect the two LED panels together to form a single 8x64 matrix.
3. Connect the ESP to the batery pack with USB cable

One LED connector should remain unused.

To control the hat, connect to the Wi-Fi network it creates, then open a browser and go to 192.168.4.1 to access the control page, just like in the photo.

Enjoy! 😊
