[otw_is sidebar=otw-sidebar-1]ATmega8 Microcontroller Project With Proteus SimulationATmega8 Microcontroller Project With Proteus Simulation. I will be able to discuss concerning street lightweight management victimization ATmega8 microcontroller. during this article, I’m justify you the way the road lightweight works, principle of street lightweight, elements I’m victimization during this project, and their applications. Therefore let’s begins.

Auto Intensity management of Street Lights

Street lights area unit controlled manually in past days. Lately automation of street lights has emerged. However one will observe that there’s no high intensity in peak hours i.e. once there’s no traffic and even in early mornings. By reducing the intensity in these times, energy may be saved to some extent. There areas unit several ways to save lots of the facility like shift the road lightweight on detective work vehicle, Street lightweight dominant victimization LDR and relays etc. They planned circuits management street intensity by scheming the height hours. Most ordinarily found street lights area unit HID or High Intensity Discharge lamps, that consume a great deal of power. So as to save lots of energy, the circuit’s area unit designed with high intensity LEDs in situ of HID lamps.

ATmega8 Microcontroller Project With Proteus Simulation

The main principle of this project is to regulate the intensity of street lights victimization PWM. Peak hours of a choose space area unit measured and consequently PWM signal is modify by microcontroller to increase or decrease the intensity of street lights. These peak hours may be calculated by considering parameters like traffic density, time, and intensity of the surroundings.

ATmega8 Microcontroller


LCD display

DS1307 IC

Light Dependent Resistance

Circuit Diagram in Proteus

Let’s start discuss the connection of this project. The main component is Microcontroller ATMEGA8. It consists of 28 pins. The microcontroller pin 6, 11, and 12 are attached with LCD pins RS, RW, and E. the pin 2, 3, 4, and 5 are connected with D4 to D7. Pin 27 and 28 are joined with DS1307 IC 6 and 5. On the right side of microcontroller pin 17 is connected with LED to indicate us.  


We use each LDR and RTC within the circuit for the subsequent reason: if solely LDR is employed, then there’s no likelihood of saving any energy because the street lights can glow as shortly because the intensity of sunshine on LDR decreases and once the intensity will increase, the road lights area unit turned off. If solely RTC is employed, the road lights area unit turned on and off at predetermined time regardless of the surface lighting conditions. Once the device is turned on, RTC starts with the predetermined time within the code. The microcontroller waits for the signal from LDR and once the intensity of sunshine on LDR decreases, the output of the microcontroller is activated and therefore the street lights begin to glow. This event happens only if this time is within vary of predetermined time i.e. solely when 5PM. The lights still glow at full intensity up to three AM. Once the time reaches three AM, the intensity of the road lightweight step by step decreases and can put off either at six AM or once the sunshine on LDR in increasing, whichever is 1st.

Auto Intensity management of Street LightsAdvantages:

  • Power wastage may be reduced.
  • Using junction rectifier array reduces the value.
  • Using of RTC and LDR produces correct results.


Guys this is not it. I promise you will get these informative lessons in future. Till then take care and have fun.



  1. An interesting discussion is worth comment. There’s no doubt that that
    you need to publish more on this topic, it might not be a taboo matter but generally folks
    don’t discuss such issues. To the next! All the best!!
