Bike Lock

I Designed smart lock which can be Bike Lock open and closed using password sent from Android smartphone over Bluetooth . 

This smart Bike Lock is the secure, simple, and easy to manage your Bike's lock. This lock needs no need keys and the lock is attached inside the Bike and you can control it from outside the Bike using Bluetooth. As the lock is inside the Bike there is no way to break the Ignition Key by a thief. An android application is required to open and close the lock and I will explain the details how you can develop an android app . A password is sent to the lock using Android app and if the password is matched to your preset-lock password then the lock will be open and sent a feedback to your phone like the lock is open.

Bluetooth control smart door lock is very simple. I have designed android application in such that it sent a command with the password. Actually I set two command, one is "OPEN -" and another is "CLOSE -" and password may contain any digit, later or symbol or combination of them as you like. In the app I used two buttons one for open and another for closing Key. When password is given to password box and open button is clicked than app joint the "OPEN -" command with the password and sent it to Processor. I add '-' sign with command for that I will separate command and password by using this '-' . After receiving the string from phone to Proceesor program separates command and password from the receive string and save them into two separate variables. Then check the password first, if password matched with saved password then open the Key for "OPEN" command, and close the Key for "CLOSE" command. "-" helps to separate command and password.
