Electronic security code lock system

Hi friends, This is a video for testing operations, your comments and suggestions are very helpful for next version of this system. If you have any idea we can work together for developing system. Here you can get information about hardware configuration, user operations and silent operations. 

Hardware Configuration:

- 16 x 2 LCD User interface display

- Password Input by 4 x 3 keyboard  matrix with 0-9,* and # keys are in use

- Stepper motor is connected for locking and unlocking operations.

- There is an option for Relay, Servo Motor, DC Motor or Electro Magnet also.

- There is a green and red light indication.

- If door is locked red led will on, or on unlock green will on.

- Buzzer indication for errors and ok states

.

User Operation:

- For first time default password is 1234 then user can it by new password.

- Enter correct password for unlocking operation.

- System will gives error message for each wrong operation.

- Only unlock on correct password.

- User can change password by pressing 9999.

- It will ask for current password,

- If it is ok then ask for new password, then display it for 2 second.

- User can lock door any time by pressing * (Star) button.

- In door unlock mode as well as in password change mode.

Silent Operation:

- On system starts, stepper motor will find the home position using lever switch

- It will getting input from external lever switch

- When get input from lever switch, it will conform home position.

- In home position door is in lock mode.

- Stepper motor is in release mode (power off mode) after each operation.

- This operation is helpful for power saving. 

- Password will save in microcontroller memory.

- In power off condition circuit will remember password without any battery backup.

- When door is unlocked and user will press * then it will give message for already unlocked condition.

Thanks for your attention.

Automatic Starter for Submersible Pump

Printer cable LCD display

Sixteen character in two line liquefied crystal display was used in this project. Data was communicated by eight data line from computer’s printer port, so using software user can send data to LCD, and as per information text was display on LCD. This project is can be used for displaying message for general people, advertisement and for the information display.

Communication: LPT Port

Motions tracking using specific colour and webcam

Using vvvv Language one colour tracking application is successfully done by me. Using this application user can mark the particular thing with specify colour and then using webcam computer can identify that particular colour and shows the x and y position of colour. Using this application user can get many output operation like getting x and y position, play movie or sound etc.

Software Part: vvvv

Communication: WebCam

Door open indicator

Light dependent resistor changes the resistance as per light intensity using this principle this project is done. Light depended resistor is attached with door frame so we can get level change as per light or no light. This output is connected with driver circuit and then it was connected with computer, so when ever door will open or close user can get information in computer and user can also select some operation like play sound, movie etc. software part is done using visual basic language.

Macro Ring Light for SLR Camera

In macro photography, providing good illumination to subjects can be quite a task. Especially when the distance between the lens and the subject is less. While using a ring light can take care of most situations, a customized ring light designed to be a continuous light source for macro photography can also do the trick. This ring light was made by using extra bright white light LEDs. Ring light can be operate using external re-chargeable battery as well as power supply, so because of that there is no major problem for power.

idea: Better Photography

Variable and Regulated power supply

Power supply unit is used in every electronics project so for exemplifying how power supply unit is work this project is done in lab. There was two type of power supply was done, one is variable voltage and second is regulated power supply. In variable voltage power supply user can vary the output voltage as per requirement and in regulated power supply user can get fix regulated voltage as output.

IC: 7805 & LM317

TBA810 7 Watt audio amplifier

Seven watt audio amplifier project was also done in lab using TBA810 chip. Using two chip user can get stereo output. Simple and small audio amplifier project is done for exemplifying the audio amplifier system.

Amplifier: TBA810

Electronics Dice

In this project AtMega16 microcontroller is used for display the functions of microcontroller. On pressing switch user can get random number on seven segment display. User can use this unit for playing dice game. Here two display character are showing two different no that no will be always less then six and for final result user has to add both no for playing game. Like here two numbers are 2 and 6 so final number is 8 and user has to move eight step in game.

Controller: ATMega16

Firmware: WinAVR

LPT Controller

In this project we are using 5 different switches interfaced with the LPT port. Depending upon the activation of the particular switch, appropriate pre selected program will be executed. Software is written in Visual Basic Program. This software detects interrupt from LPT port. Here user can define any full screen Flash movie, or any other exe file to run.

Software Part: Visual Studio

Communication: LPT Port

Input Type: Micro Switches
