Making a Robot Butterfly goes beyond aesthetic appeal—it requires managing inputs, outputs, and coordinating them seamlessly. This project is ideal for beginners, as it leverages ESP32 and the accessible FreeRTOS API through the Arduino IDE. In this talk, we’ll delve into code that enables smooth coordination between the butterfly’s flapping wings, lights (outputs), and environmental sensors (inputs)—and relate these to RTOS principles. This creates a responsive and interactive experience with its surroundings. Whether you're an embedded systems engineer, hobbyist, or creative technologist, this session offers valuable insights into breathing life into robotic creatures through embedded programming. https://github.com/RobotGrrl/RobotButterfly/.
