Overall Description:

A GUI created in C# is used to input user-pass pairs into a file and is stored in the mbed through a USB port. The security door lock accepts input (a password) from a capacitive keypad. After a password is entered, it is compared to existing passwords within the file created by the C# program. If the password is correct, a servo is activated (acting as the locking/unlocking mechanism) to allow the door be opened. If incorrect, the door will remain locked and the user can try to input another password. For every attempted access, the mbed (via WiFi chip) provides a time stamped log over HTTP.
