8085 based projects for students

You can create following 8085 project using 8255

1. Traffic Light Control System
2. Controlling The Stepper Motor
3. Temperature Control System
4. Blinking LEDs In Circular Pattern

Out of these four projects, blinking LEDs in circular pattern is very simple as hardware required to create this project is minimum and coding is also very easy....

Temperature Control System needs sensing circuitry, analog to digital converter and circuit required to control the controller making project quite difficult.

Project On Controlling The Stepper Motor is easy. Its coding is the simplest but it obviously need one working stepper motor.

Traffic Light Control System is also a good project to opt for but it requires around 12 transistors and 12 relays.

8051 based project for electrical students

(AT89S52) Prepaid Energy Meter


this project is based on implementing a similar technology like prepaid cellphone or prepaid dth home service in electrical power utilization generally for domestic costumers

this instrument we are calling prepaid eneargy meter this has provision for tariff indicator and gives an alarm sound to consumer before the whole amount is reduced.

working of the instrument:

Every domestic consumer can buy a prepaid card (is nothing but an EEPROM IC) with a password stored inside it using a Micro controller program. The memory card is available at various ranges ie. Rs 500, Rs 1000, Rs 100 etc.In this instrument we have given the name for memory card as prepaid energy card. When the consumer insert a prepaid energy card into the card reader which is connected in prepaid energy meter with tariff indicator kit.Then the card reader will read the stored password and delete the information from the EEPROM IC using the MC program. So that the prepaid energy card cannot be reused by others. Suppose if a consumer buy a card for Rs.500 he can insert this amount through the card reader so that prepaid energy meter with tariff indicator kit will be activated. According to the power consumption the amount will be reduced. When the amount is exausted, the relay will automatically shutdown the whole system.
