How can make a electronic based door lock

  There are various interface design/boards available which will generate a TTL logic high on receiving a text message, phone call or any other sensor. Use this input on one pin of microcontroller (uC). Based on this momentary signal, uC will make another pin high(and keeps it high - this is important!!). This pin can be connected to a transistor to trigger a solenoid. The solenoid pulls the latch opening the door!!

  Use DTMF that is the commonly used tool for this remote control thing and it is easy to implement as well

  Anand Tamariya,Thanks for the contribution i will be glad if you can elaborate on the uC

  we have door lock technology in various concepts. but coming to the device, you can notice across the ATMs we have a magnetic device where it can get magnetized using 12v supply and logic can be done using microcontroller so it will be un magnetized and magnetized acording to ur inputs like GSM operated, DTMF ,zigbee,RFID ,smartcard etc. so mainly you need to go for selection of Door Sensor.

  If you haven't worked on uC(micro-controller) before, that in itself is a big project.

  You should pick up controlling LEDs using a micro-controller as your project.

  How can we make this door lock so that you can operate it by a text message or phone call(signal)...Need Suggeestions please

  Use of microcontroller is a good option better u choose arm7 or max232
