In this project, an automatic headlight dimmer which uses a Light Dependent Resistor (LDR) sensor has been designed to dim the headlight of on-coming vehicles to avoid human eye effects. This automatically swit
ABSTRACT This automatic emergency led light used in night at emergency time when the power cut or off by some region. This emergency light takes 230V AC and it converts it in 12V DC and charge the battery which is used in this circuit. The power of the battery is used that time when ...
Two 555 IC stages can be seen the proposed design. The IC1 stage is wired as light activated switch using an LDR as the sensor. The relay associated with IC1 is held deactivated during day time and vice versa. IC2 is configured as a set/reset latch flip flop or bistable stage wherein...
To avoid such incidents, the automatic headlight dimmer circuit can be used. This circuit consists of light-dependent resistor (LDR) sensors and a night vision camera to sense the light from the approaching vehicle that comes in opposite direction. Then, the light signals are processed using an...
