Here, we will implement this project by using 555 timers IC. Other basic components which we used are power supply, Light Dependent Resistor (LDR), Relay and Light emitting diodes (LEDs) which we are using in place of a light bulb. A. 555 Timer IC The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. The IC was designed in 1971 by Hans R. Camenzind under contract to Signetics, which was later acquired by Philips. Depending on the manufacturer, the standard 555 package includes 25 transistors, 2 diodes and 15 resistors on a silicon chip installed in an 8-pin mini dual-inline package. Variants available include the 556 (a 14-pin DIP I. INTRODUCTION treet lighting provides a safe night time environment for all road users including pedestrians. Research indicates that night-time vehicular accidents are significantly reduced by provision of street lighting. It also helps to reduce the fear of crime, and encourages social inclusion by providing an environment in which people feel they can walk in hours of S combining two 555s on one chip), and the two 558 & 559s (both a 16-pin DIP combining four slightly modified 555s with Discharge & Threshold connected
