Firmware for an ESP32 FireBeetle that drives an Adafruit 7-segment display (I2C backpack) and exposes a local web interface for timer modes and WiFi management.

Web interface

The built-in server serves a Timer Control panel in the browser:

  • Stopwatch and Countdown modes
  • Quick presets: 10 Min, 5 Min, 1 Min
  • Manual minutes and seconds fields plus Start
  • Reset WiFi to clear stored credentials when you need to re-provision the device

Hardware

  • ESP32 FireBeetle (v1.0)
  • Adafruit 7-segment display with I2C backpack
  • Breadboard and jumper wires (SCL, SDA, VCC, GND)

Software

  • PlatformIO project; see platformio.ini in the repo for board and library configuration.
  • The repository also includes Android and firmware subprojects for a fuller stack around the same device.

Quick start

git clone https://github.com/antoinebou12/ESP32-7SEG.git
cd ESP32-7SEG

Open the project in PlatformIO (or Arduino IDE with equivalent libraries), build, and flash the ESP32. After boot, check the serial monitor for the device IP address, then open it in a browser on the same network to use the web UI.
