Security Vault Attempt 3
Locked Box Arduino Project This is the circuit diagram that I followed on instructables. Unfortunately the keypad I used was slightly different compared to the one used in the locked box project on instructables. The key difference is that the keypad uses a 3x4 keypad while I am using a 4x4 keypad configuration. Therefore I have had to adapt my hardware and code for these differences. This image was taken before the code was edited however the Arduino responds to some keypad presses and the green LED shines. Therefore as this was quite a positive result, this convinced me to pursue this design. Bibliography & References http://www.instructables.com/id/LOCKED-BOX-Arduino-Keypad-3x4-Servo/
