Project 2 : Light alarm system (LDR,BUZZER)

As you probably know the LDR is a light dependent resistor. Normally the resistance of an LDR is very high, until the light falls on and the resistance will change by reducing.

In this project we are going to make an alarm (the Buzzer giving alarm )when there is no light falling on the LDR sensor and at the same time blinking an LED.

this project can be applied in a place where light is needed constantly. and whenever the light goes off the system will directly give the alarm.

Components to be used on the Menya IoT Kit.

1. LDR sensor

2. Buzzer

3. Arduino Nano

4.Red LED
