Story

The idea is simple, but the development not so much hehe. By a button on a board connected to Internet, activates the sound of a melody (whose mp3 file you have selected) in another board connected to Internet too (the Doorbell).

1 / 2

STEP 2: Flash the code on Cloud Editor

1 / 3

STEP 4: Select your prefered song (mp3) and save on a root of a micro SD Card

After, put the microSD in LinkIt ONE Slot, and toggle mode to SD (SD/SPI).

STEP 5: Upload sketch for LinkIt ONE

1 / 2

STEP 6: Create trigger for both boards

1 / 3

STEP 7: Test and Fun!

thx for read, and don't forget respect this ;)
