A small project combining ESP8266 with a vintage Soviet Nixie tube from the 70s to create an artistic clock

The P-Bit is a compact, modular IoT platform designed for hands-on STEAM and sustainability education. Equipped with temperature, humidity, light, sound, and soil moisture sensors, it allows students to collect real-time environmental data, analyze trends, and connect to the cloud for deeper insights. It features an ESP32-WROOM-32E processor with Wi-Fi and Bluetooth connectivity, a 1.8” TFT display, a rotary encoder, and GPIO/I²C expansion for additional sensors. Students can monitor microclimates, optimize irrigation, and study noise pollution through an intuitive interface. By integrating IoT and data science into the classroom, P-Bit helps address the urgent need for climate literacy, empowering the next generation with the tools to understand and protect the environment. More than just a sensor, it is a gateway to smarter, more sustainable learning.

This is an interesting and simple to make two player Arduino game that can be made in less than a day.
