In StockA Panic Alarm Button is a simple safety device that, when pressed, immediately activates a loud alarm, buzzer, or alert system to signal an emergency or request for help. It’s commonly used in homes, banks, hospitals, and personal security systems.
Description
The Panic Alarm Button is a compact, user-activated emergency alert device. When someone feels threatened, is in distress, or needs urgent help, pressing the panic button instantly triggers an audible or visual alert. The system is simple to build using basic electronics: a push-button switch connected to a buzzer or siren circuit.
In more advanced systems, the button can also trigger a wireless signal, send SMS alerts via a GSM module, or connect to an IoT or security system. However, even a basic version with a loud buzzer can be life-saving in emergencies by drawing attention or scaring off intruders.

1.Home Security
1.Easily alert neighbours or authorities when in danger.
2.Bank & ATM Security

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.
