How to make a Laser Security Alarm System at Home on a Breadboard HD Circuit Diagram Because, in this tutorial, we are going to make a "Laser Security Alarm Circuit". Along with the laser, the circuit uses the LDR as its key component. The electrical characteristic of the LDR is where the light increases, and its resistance decreases. Because of the higher resistance, the circuit does not operate until the light falls on
Here is a basic idea of how you can make a laser security alarm using an Arduino and an LDR sensor: Materials needed: Arduino board; Laser diode; LDR sensor; Buzzer; Breadboard; Jumper wires; 220 Ohm resistor; Steps: Connect the LDR sensor to the breadboard. Connect the 220 Ohm resistor to the LDR sensor and connect it to the ground pin on the
How to Make a Laser Security System Using Arduino and LDR Circuit Diagram
A laser-based security system is a type of security alarm that uses a light sensor and laser light. In this tutorial, we are going to demonstrate a circuit of a laser security alarm system that will detect any irregular activity and will produce sound using a buzzer. One of the main components of this circuit is LDR.
If your alarm circuit is powered by 4.5 volts (three AA batteries), then it is possible to power the laser pointer from this battery pack as well. All you have to do is connect the terminals of the laser pointer to the batteries of the alarm circuit. One terminal of the laser pointer is a spring that sticks out of the internal circuit board.
