My daughter asked me if I can create a box where she can put her stuff and where she can lock it from her little sister. "Sure, I think I can do something like that!" That is how this project came to life.
I was thinking what might be a good security box for a 9 years old (at the time of the project). I came up with few requirements
- Visual effects - Adding sounds and light help to know what the device is doing
- Easy to use - the 4x4 keypad is a nice and easy clickable keypad
- Secure - ok this is no safe of course, but using the RadioShake enclousure with a servo and a little bit of 3D printing was enough for what I needed.
- Portable - needs to run on batteries.
To achieve the above 4 points I collected all the components that I needed (see list below) and started coding and building. You can find the code here If you are wanting to try this by yourself here is the list of components I used
- 1 Arduino Uno
- 1 Servo
- 1 RGB LED
- 1 4x4 keypad
- 1 Piezo
- 3 resistors (330 ohms)
- multiple color wires
