README
README.mdESP32 14-Segment Ticker Board
A custom-built ESP32-based project using 14-segment hex displays to show real-time data like a clock, stock prices, temperature, and a chess timer.
What It Does
- Pulls real-time data via Wi-Fi
- Displays info on 8 14-segment displays
- Controlled with 7 physical buttons
- Runs on battery with power management
Current Modes
- Temperature from 2 i2c sensors
- Real time clock accurate to ~1 second
- Stock Price for any ticker symbol you input
- Chess clock with 5 differet base times and increment
Photos
Finished Board!
Shows live temperature readings in temperature testing video and accurate clock in clock testing video
Schematic and Layout
Code Overview
Firmware is written in C++ and manages:
- I2C communication with display drivers
- GPIO input from buttons
- Wi-Fi data fetching
- State switching between display modes
Buttons presses trigger interrupts which are then handled and change state machines to change or move within modes.
📚 Notes
I designed and built this project as a personal challenge to deepen my embedded systems skills. The board and code were developed from scratch, and photos illustrate the final product.

Questions
How big is the TickerPCB PCB?
It measures 158.5 × 60.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TickerPCB use?
106 parts, built around the ESP8266EX, MCP73871EV, MCP9808-E/MS and MAX6955AAX. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TickerPCB KiCad files?
From the hulonoj/TickerPCB repository on GitHub, at the commit this page was made from: the board is PCB_Files/TickerPCB.kicad_pcb and its schematic PCB_Files/TickerPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TickerPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask hulonoj before reusing the design.
