This is the simplest working electronic circuit anyone could build. This Circuit is the Electronics version of
The Pictures show the exact places to mount on the breadboard. You can always follow the circuit diagram for easy understanding. Note the polarity of LED and place them on breadboard.
This is how this circuit works if you are interested. When a transistor is ON it allows current to flow through it so that the LED above it will light up.The two capacitors C1 and C2 will alternate between being charged and discharged and thereby turning the transistors ON and OFF.
This circuit senses the light intensity from surroundings and find whether its day or night. A light sensor known as LDR( Light Dependent Resistor) whose resistance varies with Light intensity is used to detect the darkness and automatically turn ON the LED and Turn OFF the LED when there is Light. LDR behaves based on the below mentioned conditions. A pair of Transistors are used to Switch the LED (Load).
High Resistance on LDR= Darkness
Low Resistance on LDR = Brightness
Fun Fact: If you are wondering how Solar Street Lights turn ON and OFF automatically, Similar Circuits will be installed in them.
Connect all the components on the breadboard and power it using the 9V Battery with correct polarity. Cover the LDR Darkness Sensor to test the circuit. The LED Should Turn ON if LDR is covered and turn OFF when Light Falls on the LDR Sensor.
This circuit can be used in living area or garden area as a emergency lighting when there is sudden power outage and can automatically turn ON Light.
This circuit can be combined with a Relay Circuit to Switch 220 V lights. Note: DO NOT attempt this if you are not sure what you are doing because 220 V is hazardous.
