Project Microcontroller MCS51 in Assembly language
base on microcontroller MCS51
The process begins with a diagnosis of hearing threshold pressing the
start button. If the patient heard a noise, then the patient should
press the Interrupt key, so that the microcontroller can record the
amplitude and frequency. On this project, the system uses bank-based
oscillator opamp 741, digital to analog component DAC0808 to regulate
amplitude and frequency components of 4051 to choose which would be
issued to the speakers. The whole system is controlled by a microcontroller
dot matrix 5x7
reading Keyboard PC PS2
Some time, we need to get input data with more complex character. In
this way, we can use PC keyboard PS2 to get data character. Interfacing
keyboard PC with microcontroller only needs 2 bit PORT.
call base on 8051 with communication RS485
A nurse call button is a button found around a hospital
bed that allows patients in health care settings to alert a nurse or
other health care staff member remotely of their need for help. In this
project, nursecall used to provide an alarm that will call the nurse
to the infirmary, nursecall triggered by using, the sound of crying
babies and baby bedwetting.
to Drive Printer Dot Matrix
Old printer that we used to print data from old komputer using LPT,
now we can use this printer dot matrix to print data from microcontroller.
6. Driver motor
DC with PWM
PWM is pulse width modulation, the important think that we can use to
control motor DC or AC. In This experiment, we use timer 0 and timer
1 to generate PWM.
to build Sphygmomanometer
A sphygmomanometer or blood pressure meter is a device
used to measure blood pressure, composed of an inflatable cuff to restrict
blood flow, and a mercury or mechanical manometer to measure the pressure.
It is always used in conjunction with a means to determine at what pressure
blood flow is just starting, and at what pressure it is unimpeded. Manual
sphygmomanometers are used in conjunction with a stethoscope.
color sensor TCS230
TCS230 is a color sensor that can read color from solid object. This
sensor is come out with frekuensi that we can chose with 4 pre scaler.
The sensor output 4 frequency, RED, GREEN, BLUE and CLEAR and then microcontroller
read the frequency and convert to color.
temperature control system on water bath
Waterbath is a laboratory equipment used to stabilize
the temperature of the sample through a temperature controlled water
medium, where the temperature, which is between 30 0C to 40 0C by setting
the timer 1 minute to 15 minutes.
In order to maintain the desired temperature stability, first heat the
water by using a heater. Then once the desired temperature is reached,
the heating will be controlled heater. When the temperature setting
below the heater will turn on and if on top of the heater temperature
setting will die, so the temperature will be maintained at the specified
base on MCS51
A spirometer is an apparatus for measuring the volume
of air inspired and expired by the lungs. A spirometer measures ventilation,
the movement of air into and out of the lungs. The spirogram will identify
two different types of abnormal ventilation patterns, obstructive and
restrictive. There are various types of spirometers which use a number
of different methods for measurement (pressure transducers, ultrasonic,
