This repository provides directions and code necessary to create an ESP-32 powered E-Ink text display that can be updated from a web browser located anywhere on the globe.

• Materials Required
• Setting Up Supabase
• Hardware Assembly
• Software Setup
• Alter the Code
• How to Use

• ESP32 - Amazon
• E-Ink Display - Amazon
• Supabase Account - Supabase

1. Create a Supabase account

2. Create a free Supabase database

3. Note your API url and key

1. Connect your esp32 to the e-ink display using the attached cables

   • The exact connections will depend on your model - use included pinout guide

2. Plug your esp32 into your computer

1. Install Arduino IDE

2. Connect your esp32 to Arduino IDE

   • Configure your IDE with the right settings for your version of the microcontroller

3. Install dependencies located on lines 3-9 of messageMain.ino

1. Add your variables

   • Add the appropriate values for lines 14-17 in messageMain.ino

2. Upload this code to your esp32

1. Using the supabase table editor, alter the value of the first cell to any string

2. After the message is received by the esp32, the e-ink display will update

   • This may take a moment due to the nature of the display and the code testing points of failure
