So this is going to be very broad and lacking a lot of information so please forgive me ahead of time.

I wanted to make a Blinking light with a Tone that could be set up to do either independent or both at the same time. Now here is my problem:

I have absolutely no idea what I am doing. I have looked around the forums a bit and to be honest a lot of this is another language to me. Is there any advice that you can give to steer me in the proper direction? I'll give a bit of background on the project:

The light will have to take a strong led for a bright flash
The device needs to be able to emit a tone
It should be able to be selected Tone, Flash, or Tone & Flash


Thanks in advance to anyone willing to help me a little. I understand its an extremely noob question. But at the same time I am as new to this as it gets  :)

Pssst. You're typing a message to the forum. Well, you were, anyway.

Agreed. Just look at all the foreigners trying to make "robot car fire" and stuff like that. Makes no sense to me.

Given a choice, go straight. If that doesn't work, turn right. If that doesn't work, turn left. If that doesn't work, back up.

Oh, good. I was wondering when we'd get to that.

A bright light and a bright flash are not the same thing. You assume that we know what the light is for, but that seems to have been omitted.

The device needs to be able to emit a tone

Then, the device needs to be a speaker. The Arduino can't emit a tone. Though it can make a speaker do so. How far away that tone will be audible will depend on exactly what components you end up with.

It should be able to be selected Tone, Flash, or Tone & Flash

Using what? One switch for tone, one for flash, and one for both, or one that cycles? How will you know which mode it is in? How will the device know when to flash, squawk, or both?

What is the purpose of the flashing and squawking?

What you describe can be achieved with a flashing lamp/LED, a sounder and a switch - no microcontroller needed.

It's for taking people that dont have Top Secret clearances through areas that they are not cleared to go through (ie contractors). The flash and tone alerts others to put away their classified materials and that an uncleared personnel will be in the area. We currently use these giant lamps that use a regular bulb and a huge battery. They die after an hour of use due to their age and use of a filament bulb and out dated speaker.

Hi Sarge,

OK, this can be done.. maybe an Arduino isn't necessary though.

The packaging of this, how it is carried / worn, the battery type and how it is changed / recharged, just How Bright and How Loud you need are questions you need to answer first.

Two 555 Timers and a small speaker in a plastic enclosure would probably be loud enough.

There are small Strobe Lights the size of a small flashlight that run on 1 or 2 C cells for hours. 

See this page on the ArduinoInfo.Info WIKI: http://arduino-info.wikispaces.com/Popular-ICs and see the 555 sections and the links to How-To.

Start at Radio shack??

If its a static installation, like a wall switch by a door, then its just a matter of wiring some simple 555 timer circuits with a selection switch.

There`s loads of 555 circuits out on the web, here`s another one
