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.

Acquiring accelerometer data

The accelerometer is one of the most common sensors that's incorporated into the IMU.

In this recipe, we will develop an application to read the accelerometer measurements from the MPU-6050 IMU with a frequency of 50 Hz. The measurements will then be transmitted over the serial so that they can be acquired with the Edge Impulse data forwarder tool in the following recipe.

The following Arduino sketch contains the code that's referred to in this recipe

Getting ready

The accelerometer is a sensor that measures accelerations on one, two, or three spatial axes, denoted as X, Y, and Z.

In this and the following recipes, we will use the three-axis accelerometer that's integrated into the MPU-6050 IMU to measure the accelerations of three orthogonal directions.

However, how...
