Interfacing of EasyVR with Arduino

Hello friends, I hope you all are fine and having fun with your lives. In today's post we are gonna see Interfacing of EasyVR with Arduino UNO. In the previous post, we have seen Getting Started with EasyVR Commander. It was quite simple and if you follow the steps carefully you wont stuck anywhere but still if you into some trouble i am here.

Interfacing of EasyVR with Arduino UNO

• First of all, download the Arduino Libraries for EasyVR Shield, you can easily find them from the official website of EasyVR.
• Simply connect your Arduino UNO with computer.
• Open the Arduino Software and copy paste the below code into it.
• Burn your code in the Arduino Board.
• Now open your Serial Monitor of ARduino UNO, and you will first see the message saying EasyVR Detected.
• Now speak any of the command you saved in the board on mic and you will see when the command match the serial terminal will send a specific character.
• You can change this character if you want to by make a simple change in the code.
