This is final result for our project.
this project use 2 circuit which is sensor n timer.
this project is quite simple but have multifunction
there are some video of this project,

Automatic Water Level Controller

The one described here is built around timer NE555 and inverter buffer CMOS IC CD4049.
It uses readily-available, low-cost components, and is easy to build and install on the over-head tank (OHT) to prevent wastage of water.
The circuit works off a 12V battery or 230V AC mains using a 12V adaptor.
The three sensors built from non-corrosive metal are fitted to the over head tank to prevent wastage.
As water is consumed and its level falls below sensor,the motor restart.
Also can manually start and stop motor using switch.

SMART SINK

Specificatian :-
- This Smart Sink have 3 pipe that function using motion sensor.
- Every pipe have its function, the function of the first pipe is flow out the water,
the soap and the last pipe operate to dry the hand.

- I made this project for help people easy to clean their hand because our

product will flow out water, soap, and dry the hand automatically.

-This product also save water because it control by the sensor.

Hardware and Software :-

- PIC 16F87X 28/40-Pin 8-Bit CMOS FLASH microcontroller

- DC Water pump motor

- Infrared sensor

- Transformers 240V to 24V

- C coding, Protues

Electric Cook

This project involves making an electric device which functions to cook rice, cuisines, deserts etc. The cooker's functionalities and benefits are:

-Use electricity to heat
-Adjustable temperature
-Set timer
-Set temperature limit
-Cooking faster
-Auto-stir
-Safety
-Mobile (friendly especially for college students)

Active Voice

I came up with this idea of activating almost every electrical items in a house (or maybe just a room) -eg: lamp, fan etc- via some sort of a voice recognition system. I'm not quite sure about the costs and sensors required to accomplish this but perhaps, it may need a few sensitive voice detectors (microphones). This system works just like the voice recognition software used in OS Windows Vista and se7en.

Smart Mail-Box

Smart Mail-Box is a combination with mailbox and the electronic circuit.
It's function are to show the user wether there is a letter and how much letter in the mailbox. This Smart Mail-Box will operate with using the LED and siren/buzzer as a indicator and there are also use the counter circuit which be connect to the light sensor.
Based on my ideas, this project will use the five unit LED that will show how much letter in the mailbox. If there are one letter, the first LED will be turn on, if there are two letters, two LED also will be on and its continue for the next letters until there are five letters in the mailbox. After the all LED unit turn on, the siren/buzzer will turn on and produce the sound to indicate the user that there are five letters and the user need to take all of the letter.
This is just some ideas from me for this time..i hope you guys will give any feedback about this post and contribute opinions and ideas to make some addition ^_^

Project For Digital Electronic

Smart Jogger

This project used to count distance that we jogged.

Alarm will occur when we it reach the desired distance.

Advantages

Can set distance to jogs

Wearing smart jogger provides extra motivation useful in increasing your level of exercise participation

Wearing a smart jogger helps the environment and makes you more healthy.

AUTO FLUSH TOILET

In this project, its focus for sitting toilet. It operate when a person use the toilet, its have a weight. After the weight lifted (person stands up). the flash will automatically activated.
