It controls a stepper motor for direction and speed functions. The use of stepper motor is getting very popularity in the field of automation and control, in this project basic ideas are discussed about the control of stepper motors with microcontroller 8051.

MICROCONTROLLER AT89C2051 BASED COUNT DOWN TIMER:
The project performs the countdown operation for upto - 99 minutes with two seven segments display showing actual time left to activate or de-activate the connected relay. Count Up or count down timer are required in many application, so this is a useful project which trained the student to use the internal timer/counters of 8051 microcontroller.

MICROCONTROLLER AT89C2051 BASED FOUR DIGIT CODE LOCK WITH LCD DISPLAY:
One can lock the desired device with the help of this project. It will open with a selected four digit code. Security system with code lock using microcontroller 8051. This application will help to understand the interfacing of keypad with microcontroller.

MICROCONTROLLER AT89C2051 BASED TEMPERATURE INDICATOR:
 The temperature of room can be displayed at LCD using a sensitive device DS 1621.In this project digital temperature sensor DS1621 is used. The DS1621 interfacing with microcontroller is discussed in this project.

MICROCONTROLLER AT89C2051 BASED CAPACITANCE METER:
The project will check the value of unknown capacitor at seven segment display.How measure the capacitance of a capacitor using microcontroller. Off course capacitance sensor or transducer is required here.

MICROCONTROLLER AT89C2051 BASED HEART BEAT MONITOR (PULSE RATE ) :
It will check the pulse rate of a person from the finger and display it at seven segment unit.Biomedical engineering projects are also developed using microcontroller.

MICROCONTROLLER AT89C2051 BASED VERSATILE TIMER FOR SPORTS, CONFERENCE, KITCHEN OR TEL.BOOTH :
Its quite useful timer for many applications.The timer of the project is functioning based on the use of internal timer of 8051 microcontroller. The internal and external interrupts are used in this project.

MICROCONTROLLER AT89C2051 BASED ALARM CLOCK:
The unit display the time in Hr. Min. and one can set the alarm also for a desired time at Seven segment display.

MICROCONTROLLER AT89C2051 BASED AUTO FISH FOOD FEEDER FOR AQUARIUM:
One can set a time to feed fishes using a mechanical arrangement to feed once a day.

MICROCONTROLLER AT89C2051 BASED BRAINWAVE FOR TENSION RELIEF:
 The timer based flashing light with frequency control can be useful for person to get rid of tension at night while on bed time.
 
MICROCONTROLLER AT89C2051 BASED AUTOMATIC FLUSHING SYSTEM:
It will switch on the motor pump for flushing for a time duration whenever the urinals/toilet is used by someone.

MICROCONTROLLER AT89C2051 BASED SPEED MONITORING SYSTEM FOR MOTOR – TACHOMETER:
