This senior project is a combination lock solver, powered by an Intel® Galileo Gen- 1 microcontroller board. The Galileo controls a stepper motor and solenoid for the lock manipulations and communicates with an Android App using a serial Bluetooth module as shown in Figure 1.

The Galileo processes user information from the Android App to determine the possible lock combinations. Once the possible combinations are determined, the Galileo works its way through the possibilities by inputting them into the lock and checking for success until the lock is opened, as shown in Figure 2. When the lock is opened, the system sends the correct combination to the user via the App.
