Love box

Hello guys! In this project, we will make love box. When you give this box to your lover, He/She opens, it automatically speaks "I LOVE YOU". For making this I am using using DF player mini module for audio playing and I am also using speaker and 3.7volt battery. I copy audio file into sd card and put into the DF Player mini. You can use you own sound or audio. you can make this love box at home with very little effort.
