[RESOLVED] External Device

[dclamp]

Ok, i am planning to enhance my Point of Sale project by adding a feature where you can add a "alarm button" (a physical object)

Now, I plan it only to be a simple circuit and i want to know the best way for it to communicate with my project, if possible and what code i would need for it.

I am not sure what way to do it that it will work with. I know USB has 5 volts of power, that could be my power source but how would i connect it with my program?

I hope i have made sense here... if not, i will try to tell you better. thanks

Don't you want to use your speaker instead? Play an alarm sound or use the system beep?

Make your life much easier.

Take this for instance...

A guy walks into a store using my POS system, he says "Give me your money, this is a stickup." The cashier hits the alarm button, "BEEP BEEP BEEP *siren sounds*". the robber shoots the cashier

....

yeah, what i would want it to do is like lock the system and everything. Maybe call local law enforcement

LOL. You didn't specify where your alarm located and for what purpose. So you want to alarm who and where?

is this necessary for the proper code?

at this time, what i want it to do is lock my program, and POSSIBLY make a call to some one (Store Owner, Manager, Law Enforcement, etc..)

Yes, every detail is necessary for us to give a more logical and realistic solution.

Hmm, now this is interesting. How about using winsock to send data to someone (police or whoever)

Say send an alarm to the Police using winsock.

Ok this is crazy. How about instead of an alarm, if you're really on to interfacing, then go for an "automatic gun firing in front of the bad guy's leg or thigh"... by hitting the pedal control. Is firearms prohibited in your place?

i dont have "a place" this project is for fun right now, but if i ever do finish it i plan to sell it

fyi, your not helping very much

If you're more to security purposes then there are lots to be considered. If you're planning to use internet to call an alarm to someone, then think again. What if the internet is down?

Make sure it's feasible depending on the location. It's a matter of life and death.

I'll go for a handgun.

ok. i still want to do what i plan to do. I will not add the call option then...

Add a webcam to the computer and make it record the thief. Then if they do make it out with the cash, u have a good quality image of the person, in colour as well (since most security systems are black and white). Also possibly record their voice as well.
