Building A Voice-Activated Home Assistant

When we think of home automation, our minds usually jump straight to expensive devices that require professional installation. What if there was a way to Create a home assistant that won't break the bank? With the help of a little DIY magic and some voice recognition technology, You can create your very own voice-activated home assistant. In this article, we'll be showing you how to build "Otis v1.0", a budget-friendly home assistant that won't cost you an arm and a leg.

Materials Needed

Before we get started, let's take a look at the materials we'll need to build Otis v1.0:

• Arduino Uno
• Breadboard
• SD Card Reader
• Voice Recognition Module
• Relay
• Extension Cord
• Popsicle Sticks
• Aux Cord
• Male-to-Male Jumper Wires
• Female-to-Male Jumper Wires

Building Otis v1.0

Attaching the Arduino to the Board

The first step is to attach the Arduino to the board. To do this, use screws or any other suitable fastener. For this project, the author used popsicle sticks glued together to hold the aux cord in place to prevent it from moving.

Connecting the SD Card Reader

Insert the SD card into the reader, and connect the 5V and Ground wires to the first two pins of the breadboard. The positive and negative wires will connect to the breadboard as well. Refer to the pin holder Diagram to ensure that everything is connected correctly.

Connecting the Voice Recognition Module

Connect the Voice Recognition Module to the breadboard by connecting the VCC or 5V and Ground wires first. Next, connect RX and TX to pins 2 and 3 on the Arduino, respectively. Do not use the actual RX and TX pins on the Arduino as they may not work as expected.

Connecting the Relay

Connecting the relay is a crucial step in building Otis v1.0. First, connect the ground wire to the first relay, N1. The 5V wire will connect to the breadboard's positive terminal. Finally, the N1 Pin goes to 5. It is essential not to remove the yellow piece on the relay as it plays an important role in operation.

Attaching the Extension Cord

Cut and expose the wiring on the flatter side of the extension cord, which is the hot side. Attach it to the relay by twisting it into the middle and left pins to make sure they effectively connect. After attaching the appliance's power cord, plug it into the wall or socket.

Uploading the Code

Finally, upload the code into the Arduino. The code used for Otis v1.0 is long, but it can be accessed in the article's description. It is essential to note that if you have a different voice recognition module, this code may not work.

Tips and Tricks

It is crucial to follow the steps correctly to ensure that Otis v1.0 works correctly. If you run into any issues, refer to the supporting media found in the article.
