Hi Folks,

I have an issue at work where I keep forgetting to lock my desk drawers. There's a policy which means that if I get caught leaving my drawer unlocked again I'll face disciplinary actions.

The lock is a built-in barrel combination lock on the draw.

I want to build a small electronic device with beeps if:

- Its after 5pm
- A the circuit is not completed (i.e. lock lever arm is not in the up position).

I have literally no idea how to do this.

Anyone able to guide me in the right direction? Single components? Audrino? Pi?

You can just use a sensor and smarthings for things

And in the app just say to check when leaving.


If your doing it manually you just have to get the same sort of sensor and map it to your own board and get some code to check it is 1/0 at a given time and beep.

Like it! I cant see any of these which would sense 'locked' vs 'closed' though, only want I can think of doing that is having an electrical circuit complete/break when the locking bar moves to the locked position.

I've just thought, I can probably simplify this and just have an LED light blink if the draw is ever unlocked.

So I should just need a battery, LED and a circuit which completes when the draw is unlocked?

If you use Slack or Outlook or whatnot could you not just set yourself a 'lock the damn drawer' reminder?
