We made arduino project that moves servo motor to turn off the switch.
We used
- Servo motor(sg90)
- DFPlayer mini
- sound sensor(FC-04)
- micro sd card
- Arduino UNO board

If we clap once, sound sensor gets signal. Then, servo moves with 110 degree. After time that we set in timer code(as for me, it was 5 sec), servo moves to 10 degree and DFPlayer plays music saved inside.
