The clap switch is a unique Arduino project, that allows remote control of devices by clapping or a voice signal. This switch is used in a wide range of electronic devices. In this post, we will learn How to make clap switch with Arduino, using an audible signal or clapping.
Electronic components that we need:
- Arduino UNO
- Breadboard
- Sound Sensor
- 1 LED lights
- 1 resistor 220 Ohm
- Electrical wires
Circuit diagram:
Programming Code:
int Sensor = A0;
int clap = 0;
long detection_range_start = 0;
long detection_range = 0;
boolean status_lights = false;
// by www.andprof.com
void setup() {
// put your setup code here, to run once:
pinMode(Sensor, INPUT);
pinMode(10, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
int status_sensor = digitalRead(Sensor); // reads analog data from sound Sensor
if (status_sensor == 0)
{
if (clap == 0)
{
detection_range_start = detection_range = millis();
clap++;
}
else if (clap > 0 && millis()-detection_range >= 50)
{
detection_range = millis();
clap++;
}
}
if (millis()-detection_range_start >= 400)
{
if (clap == 2)
{
if (!status_lights)
{
status_lights = true;
digitalWrite(10, HIGH);
}
else if (status_lights)
{
status_lights = false;
digitalWrite(10, LOW);
}
}
clap = 0;
}
}
