The definition of light night is so that night passers will be able to see more clearly, drivers will be able to drive safely and accidents will be avoided. Nightlight requires LDR (Light Dependent Resistor). The resistor changes its resistance depending on the amount of light it receives. LDR is also used to monitor light intensity level. A resistor, which reduces the flow of current in circuit, is also needed. 555 microprocessor the brain is also needed to control the flow of energy from the power supply to the components. Battery will be used to supply voltage for the circuit. We detect a light level using a LDR. The LDR then send signal to the LED providing us with the output of light. AIM The aim of this investigation is to make a nightlight. The light will be...
