How to Clapping On Off Lamp using Raspberry Pi?

You have always wanted to turn the lamps on and off by clapping while lying in your bed. In this project, we will learn how to turn the lights on and off with clapping, and how it works. We used Raspberry Pi Kit in the project.

Most of us have seen lamps flashing magically or doors opening and closing with the sound of clapping in movies. There are set assistants who close these doors and turn off the lamps in the shootings. What if we did this automatically? There are sensors that convert the sound intensity change that we expect to occur in the environment into an electrical signal. These are called sound sensors.

Details and Algorithm

In this project, we will turn the LED module on the picobricks board on and off with the sound. In our project, which we will build using the PicoBricks sound level sensor, we will perform the on-off operations by making a clap sound. As in previous projects, in projects where sensors are used, before we start to write the codes, it will make your progress easier to see what values the sensor sends in the operations we want to do by just running the sensor, and then writing the codes of the project based on these values.

Components

1X PicoBricks
1X Sound Sensor
3X Jumper Cable

Wiring Diagram

You can code and run PicoBricks’ modules without wiring. If you are going to use the modules by separating them from the board, you should make the module connections with grove cables.

MicroPython Codes of the PicoBricks


from machine import Pin #to access the hardware on the pico
sensor=Pin(1,Pin.IN) #initialize digital pin 1as an INPUTfor Sensor
led=Pin(7,Pin.OUT)#initialize digital pin 7as an OUTPUTforLEDwhile True:
    #When sensor value is '0', the relay will be '1'print(sensor.value())if sensor.value()==1:
        led.value(1)else:
        led.value(0)

Arduino C Codes of the PicoBricks


void setup() {
  // put your setup code here, to run once:
  pinMode(1,INPUT);
  pinMode(7,OUTPUT);
  //define the input and output pins
}
void loop() {
  // put your main code here, to run repeatedly:

  Serial.println(digitalRead(1));
  if(digitalRead(1)==1){
    digitalWrite(7,HIGH);
    delay(3000);
  }
  else{
    digitalWrite(7,LOW);
    delay(1000);
  }
}
