Description

VC-02 Module Based Home Automation

In this guide, I’ll take you through the process of building a project using a custom-designed PCB, which integrates an onboard VC-02 chip for voice recognition and control. I’ll also share details about how to get your PCBs fabricated through PCBWay. Let's dive into the steps, including the PCB design and assembly, so you can replicate this project.

The layout of the PCB was carefully designed to separate the relay channels from the logic circuits, minimizing interference and ensuring reliable operation.

Why PCBWay? When it comes to fabricating high-quality custom PCBs, I always use PCBWay. They offer affordable prototyping services with fast shipping and excellent support. You can get $5 off your first order, and they have special offers that include free shipping for makers. Plus, they allow you to upload and share your projects with the PCBWay community!

PCBWay also offers a handy Gerber viewer to help verify your files before production.

Next, we’ll program the microcontroller to recognize voice commands via the VC-02 module and control the relays accordingly.

Upload the code using the Arduino IDE or a similar platform. Connect your microcontroller via USB and ensure the right COM port and board settings are selected before uploading.

Power up the PCB and test the voice commands. Use a multimeter to check for voltage across the relay terminals to ensure proper activation.

If voice commands aren’t recognized, ensure the microphone is properly connected and the VC-02 module is functioning correctly.

This upgraded project demonstrates how to combine voice recognition with a custom-designed PCB to create a versatile automation system. With PCBWay’s reliable and affordable PCB fabrication, bringing this project to life is easier than ever.

For any of your PCB needs, I highly recommend PCBWay for their fast, affordable, and high-quality service. Plus, you can share your projects with their active maker community for more exposure and collaboration.

Code

Sample Code. Upgrade it according to your needs

Arduino

#include <VC02.h>



// Relay pins

int relay1 = 5;

int relay2 = 6;



void setup() {

 Serial.begin(9600);

 VC02.begin(9600); // Initialize the VC02 module



 // Set relay pins as outputs

 pinMode(relay1, OUTPUT);

 pinMode(relay2, OUTPUT);

}



void loop() {

 if (VC02.recognize("Turn on Relay 1")) {

  digitalWrite(relay1, HIGH); // Activate relay 1

 } else if (VC02.recognize("Turn off Relay 1")) {

  digitalWrite(relay1, LOW);  // Deactivate relay 1

 }



 if (VC02.recognize("Turn on Relay 2")) {

  digitalWrite(relay2, HIGH); // Activate relay 2

 } else if (VC02.recognize("Turn off Relay 2")) {

  digitalWrite(relay2, LOW);  // Deactivate relay 2

 }

}
