Arduino TinyML Projects — On-Device Machine Learning for Microcontrollers
TinyML runs trained neural networks on resource-constrained boards such as the Arduino Nano 33 BLE Sense and ESP32. Final-year projects that collect sensor data, train compact models (often with Edge Impulse or TensorFlow), quantize them, and deploy with TensorFlow Lite for Microcontrollers demonstrate real edge AI skills valued by industry.
Below are 50+ topics across gesture/motion, audio keyword spotting, tiny vision, anomaly detection, environmental sensing, deployment tools and applied systems, with the boards and software typically used.
