i had attached arduino uno with r-307 finger print sensor a 4channel 12v relay module and mp3 tf 16p player. i can control the relay with finger print sensor it turns on and of as i desire but i want to play recorded voice commands when the relay switches, for eg, when relay 1 and 3 switch on it should play file 0001.mp3 and when relay 2 switches on it should play file 0003.mp3
i learned how to use mp3 tf player but couldn't combine both the finger print and mp3 player coding
i am attaching the code for finger print sensor and relay switch do suggest me how to add code for playing music in between
