Introduction: How to Turn ON AC Light and Fan by Clap Using Arduino and Sound Sensor
How to make a clap switch?? It's really easy to make AC appliances work just by snap or clap, be careful when you are using AC appliances , if you are novice please don't try this without understanding some basic stuff about electronics.
Step 1: Components Need and How to Connect the Components.
Sound sensor (digital output)
This video I made for double clap switch but both the hardware connections are same.
Note: Make sure you are connecting the sound sensor and relay according the Program.
Step 2: Arduino Program
int Torelay = 8; // signal to drive relay
int soundsensor = 7; // input from sound sensor
boolean state = false;
if (digitalRead(soundsensor) == LOW)
state = !state;
copy the program and transfer the program to your arduino.
Step 3: Working of Clap Switch.
If you are looking for a dual clap switch take a look in this blog : http://www.labviewarduino.in/2015/01/dual-clap-switch-clap-clap-on-clap-clap.html
