DIGITAL COMPASS SYSTEM

Digital compass system is based on Dallas micro controller and FPGA Altera.
User may change the angle of slope and  it direction  and see  the changing on VGA display. Direction is mesured by digital compass communicated with i2c protocol , angle of slope with tilt sensors . DE1 board reading the data from micro controller via RS232 protocol and drawing different pictures on VGA display with 640*480 resolution(works as the graphic card). DS89C450 program is written on C51 ,FPGA code is written on VHDL .

SMART HOME

Smart home system is based on Dallas micro controller .
User may turn on/off any facility (fan f.e. ) or change the angle of windows blind (servo f.e. ) ,also you may get the temperature measure result on your PC.
Software interface is written on C# , DS89C450 program is written on C51 .
Communication between PC and micro is with RS232 connection via Bluetooth,
temperature measure with BMP180 module via i2c standard.

Car monitoring system

Car monitoring system is based on Dallas micro controller.It measures temperature ,liquid level,light level and distance.It measures temperature with DS1621 thermometer with I2C interface and shows value on LCD .Light sensor is LDR, when there is not  enough light ,system write to you "turn light on " .You may choose by switch mesuarment distance (reverse drive) .System measures distance with ultrasound sensors.Also system measures accumulator voltage with I2C analog to digital converter PCF8591.

Home security system.

Alex & Sveta

Home security system based on Dallas micro controller and P.C.
You have 4*4 keyboard to enter your code, if the entered code is correct, you see on LCD that code is correct and you may come in.
But if you don't enter the code and open the door, system detects it and makes your photo by web camera. Program on P.C recieves code Alarm via LPT, makes photo and sends it to your email. Micro controller program is written on C-51 , P.C. program written on Visual Basic .

The author of the project's idea is Elena Stahovska .

Facility controlled by phone

Adi & Asaf





This project helps to contrlol facility with 4 different objects ,you may turn them on or off with your mobile phone.
Project based on Dallas micro controller and MT8870 DTMF decoder .
When you call to its phone number, controller counts number of rings and after circuit "answers" you.
You listen that line is busy and you can turn any device with your mobile phone .
F.e when you press "1" you phone send DTMF signal , project circuit detecst it and turns device 1 on. When you press 9 you end your call. Program for project written on C-51.
This project was very good job of Adi and Asaf.

Facility control system

Eliran & Gabriel

This project measures temperature ,liquid level and frequency AC power supply,it bases on Dallas micro controller .It measures temperature with DS1621 thermometer with I2C interface and shows value on LCD ,when temperature is out of range it turns cooling or heating system,it measures liquid level with line level sensor and when level is low you see message "No liquid",
and it also measures frequency with micro controller integrated counter.
Program is written on C-51.

Tachometer with voice range alarm

Evgenii & Michael


This project is tachometer with the voice alarm .
Its measures speed of motor in round per second and show value on LCD , in time you listen
range of motor speed f.e 1st speed 2nd speed or the speed out of range .
Projects bases on Dallas micro controller with ISD1420.
Program is written on C- 51.
