The Grove speech recognizer is a module designed for application in the smart home, toy, robot or anything you would like to control with voice commands.

Overview

The board includes a Nuvoton ISD9160, a microphone, 1 SPI flash, 1 grove connector, 1 speaker connector and 1 led to show to your voice activity.

Nuvoton ISD9160 is (SoC) Chipcorder that based on Cortex™-M0, it provides performance and the energy efficiency needed for voice control applications. The microphone on grove-speech recognizer is Omni-directional.

This speech recognizer can recognize 22 commands including ‘start’, ‘stop’ and ‘Play music’. Every time it recognizes a command, it will return a value and the connected loudspeaker will repeat the command. This value can be used to control other devices like a motor or music player.

Note: The wake up word is “Hicell” (Pronounce it as one word). When it recognizes the awaken word the LED turns red and you can say the command word. If it recognize the command word, the LED will turn blue.

Note: The firmware of the module was wrote by the third party vendor, it’s not open source.

A Guide for Parents: How to Learn Electronics and Coding with the Arduino Student Kit
April 30, 2020

Schools have recently had to make a sudden and seismic shift in the way they teach. As both educators and students get used to remote learning, the onus is now more on parents to support their children through homeschool, and that means parents themselves need support. At Arduino Education, we want to help you and your children by making remote learning experiences as smooth (and fun!) as possible. Learning electronics and coding at home As parents to children aged 11-plus, learning electronics and coding with them at home may not be something you’d ever think you’d be doing. But don’t worry, it really isn’t as daunting as it sounds, and electronics and coding skills are crucial in the world your children are growing up in. About electronics and coding Learn coding and the basic concepts of electricity together with your child at home with the Arduino Student Kit. It comes with all of the electronic components you need, as well as step-by-step instructions for how to start coding. But what is coding, exactly? Well, it’s simply the language that computers understand. It’s how we tell a computer what to do. In the Student Kit, you get pre-programmed code to help you understand how it works. You could also explore drag-and-drop visual coding such as Scratch to help you get a better understanding of what coding is. Learn electronics and coding at home with the Arduino Student Kit The Student Kit is a hands-on, step-by-step homeschool starter kit for children aged 11-plus that will help them get started with the basics of electronics and coding at home. You’ll get all the hardware and software you need for one person, as well as complete guidance, step-by-step lessons, exercises, and a logbook where you can answer the lesson questions and find solutions. How the kit helps you homeschool your children This is your hands-on, step-by-step remote learning tool that will help your child learn the basics of programming, coding, and
