Rejseplanen E-Paper Display

This project is a creative implementation of a Rejseplanen bus and train schedule display using an ESP32 and an E-Paper screen. The idea is to emulate the look and functionality of the actual bus stop displays found in Denmark, but in a compact, energy-efficient form. The E-Paper display updates at regular intervals (once every minute) to show the latest bus and train schedules.

Features

• Energy Efficiency: Utilizes an E-Paper display, which consumes very little power, especially when the content does not need to be refreshed frequently.
• WiFi Connectivity: The ESP32 connects to a WiFi network to fetch real-time data from the Rejseplanen API.
• Minimalist Design: The display is designed to resemble actual bus stop displays, providing a familiar and aesthetically pleasing interface.
• Easy Customization: Modify the code to adjust the city, fonts, or display parameters to suit your needs.

Hardware Requirements

• ESP32: A powerful microcontroller with built-in WiFi.
• E-Paper Display: A monochrome E-Ink display that mimics paper, ideal for low-power projects.
• WiFi Network: Necessary for fetching data from the Rejseplanen API.

Software Requirements

• Arduino IDE: For programming the ESP32.
• GxEPD2 Library: For controlling the E-Paper display.
• ArduinoJson Library: For parsing the JSON data received from the API.
