==Debugging==

Step 1: Build circuit

Connect to keyboard

Connect OLED：

Step 2: Download the code and run. If there is compiling error, you will need [[http://playground.arduino.cc/uploads/Code/keypad.zip keypad.zip]] and restart IDE after download.

Step 3:

'''Usage：'''

After powering on the coded lock, OLED will show “Password”.
[[File:keyPadSetup7.png|600px|center|thumb]]

[[File:keyPadSetup8.png|600px|center|thumb]]

The initial password is “123456”.

After you enter the code, it will display “Welcome” and the servo will turn 90 degrees and return to zero after five seconds, which means it has been opened.

[[File:keyPadSetup9.png|600px|center|thumb]]

If wanting to change the code, you need to press “*”. OLED will remind you to enter the previous password before you want to change a new one. You can’t change the code when inputting wrong.

Step 4:
Then install Microduino-BM and the Li-ion battery and fixate to the drawer.

==Result ==

The drawer can only be opened when entering correct password. You can also reset the password and save password when there is power-off.
