“In this tutorial, I’ll be showing you how to make Alfred - the Arduino servant robot that uses Alexa-powered voice control on Raspberry Pi over a Bluetooth connection. It sounds really complicated, but it’s a great way to learn about microcontrollers, electronics, circuits, bluetooth, Linux, the internet, and programming. Also, it’s a great way to learn about something while: 1) not being entirely bored; 2) making something that you can show off to people and make them think you’re smart. Additionally, unlike other tutorials that use voice control there’s no port forwarding required (you don’t have to open up your computers to the internet and hackers), and you don’t have to pay for services (the voice control and software are all free).”
