TinyML Cookbook

By: Gian Marco Iodice

Overview of this book

This book explores TinyML, a fast-growing field at the unique intersection of machine learning and embedded systems to make AI ubiquitous with extremely low-powered devices such as microcontrollers. The TinyML Cookbook starts with a practical introduction to this multidisciplinary field to get you up to speed with some of the fundamentals for deploying intelligent applications on Arduino Nano 33 BLE Sense and Raspberry Pi Pico. As you progress, you’ll tackle various problems that you may encounter while prototyping microcontrollers, such as controlling the LED state with GPIO and a push-button, supplying power to microcontrollers with batteries, and more. Next, you’ll cover recipes relating to temperature, humidity, and the three “V” sensors (Voice, Vision, and Vibration) to gain the necessary skills to implement end-to-end smart applications in different scenarios. Later, you’ll learn best practices for building tiny models for memory-constrained microcontrollers. Finally, you’ll explore two of the most recent technologies, microTVM and microNPU that will help you step up your TinyML game. By the end of this book, you’ll be well-versed with best practices and machine learning frameworks to develop ML apps easily on microcontrollers and have a clear understanding of the key aspects to consider during the development phase.

Communicating with the MPU-6050 IMU through I2C

The dataset is the core part of any ML project because it has implications regarding the model's performance. However, recording sensor data is often a challenging task in TinyML since it requires low-level interfacing with the hardware.

In this recipe, we will use the MPU-6050 Inertial Measurement Unit (IMU) to teach the fundamentals behind a common communication protocol for sensors: the Inter-Integrated Circuit (I2C). By the end of this recipe, we will have an Arduino sketch to read out the MPU-6050 address.

The following Arduino sketch contains the code that will be referred to in this recipe

Getting ready

For this recipe, we need to know what an IMU sensor is and how to retrieve its measurements with the I2C communication protocol.

The IMU sensor is an electronic device...
