The design components:
White foam board.
The electronic components:
Breadboard.
Buzzer.
Jumpers.
LED.
Resistor 220 ohm.
Arduino.
On/Off switch,
The software :
Tinkercad.
Arduino.
The connection is done using the buzzer and the LED plus the switch button all connected to the arduino through the breadboard by jumpers and crocodile wires.
The buzzer and the LED are in sync receiving the code from arduino to make the output "sound and light" based on the code which is the SOS signal written by default timing three times.
after adding a switch to the circuit " the input component "

where the circuit only works with the switch button at first which is inserted to the foam board , then the code runs making the buzzer work with the LED at the same time making the SOS signal.
