How to Make a Talking PIR Motion Security System

Introduction: How to Make a Talking PIR Motion Security System

About: Robotic Projects (Arduino, Raspberry Pi, ESP8266, PCB, IoT, 3D, Electronics)

In this video we will make a security system that detects motion and speaks. In this project the PIR sensor detects motion and the DFPlayer Mini MP3 module plays the previously defined sound.

Step 1: Video Tutorial - Step by Step

In this video you can see the project process step by step.

Step 2: Required Hardware

Step 3: Arduino IDE Source Code

  • Upload the Sound to SD Card
  • Download the Source Code
  • Install the Required Hardware
  • Select the Board and Port
  • Upload the Code

For more information see the video tutorial.

    DFRobot's library for the DFPlayerMini is a terrible and inefficient library. If anyone want's a faster and simpler library to use with this module, I suggest using this one: You can also download and install through the Arduino IDE's Libraries Manager (search "DFPlayerMini Fast").

    Do you think you could share your circuit diagram? I'm not the kind of person that learns well from videos. :D
