Arduino Nano 33 IoT Shield for Nixie Clock

Project Descript_ion

The Arduino Nano 33 IoT Shield for Nixie Clock is an exciting project that combines the power of modern microcontroller technology with the retro charm of Nixie tubes. Nixie tubes are vintage display devices that use neon gas to display numerals, making them a perfect fit for a unique and eye-catching clock. This project aims to create a functional and aesthetically pleasing Nixie clock with modern features and IoT connectivity, using the Arduino Nano 33 IoT board as the core controller.

Project Objectives

  • Design and construct a Nixie clock with a visually appealing and retro-futuristic aesthetic.
  • Implement precise timekeeping using the DS3231 real-time clock module to drive the Nixie tube display.
  • Create a user-friendly interface for setting the time and other clock parameters.
  • Incorporate IoT capabilities for remote monitoring and control via Wi-Fi, enabled by the Arduino Nano 33 IoT board.
  • Ensure accurate temperature and humidity monitoring using the BME280 sensor.
