Learn how to build wireless "Smart Dice" using ESP8266 and Node-RED in this comprehensive video tutorial. Discover the process of creating dice that detect their orientation using an MPU6050 linear accelerometer and broadcast the information via MQTT to a Node-RED broker. Explore potential applications in escape room puzzles, such as arranging dice to achieve specific totals or following numeric sequences. Gain insights into using the Wemos D1 Mini board, ideal for portable escape room props due to its small size, battery shield, built-in Wi-Fi, and 3.3V logic. Follow step-by-step instructions for connecting the MPU-6050 sensor to various microcontrollers, including ESP32 and Arduino boards. Learn to write portable code using the generic "Wire" library for I2C components, a valuable skill for working with sensors lacking existing libraries. The tutorial covers hardware overview, wiring, power requirements, Arduino/ESP8266/ESP32 code implementation, and Node-RED flow setup. Gain practical knowledge to create interactive, tech-driven puzzles and props for escape rooms and other playful applications. Read more
