How To Use the Alarm from an Alarm Clock in Something Else?

I wanted to make an alarm type thingy, ad I want to use the alarm from an alarm clock. I don't know how though, I tried connecting a cell to the wires that were already on the alarm, but it won't work. I think it's one of those piezo-electric crystal thingies. And I know I have to have pressure on it to work. How exactly would I use it?

Wireless activated buzzer/alarm

Can someone help me with this? I need a wireless activated buzzer or alarm. Similar to the cheap wireless doorbells where you push the button on the remote and the bell rings. Release the button, and it stops. But it needs to be a loud sounding buzzer or alarm, fairly high decibels, and did I mention very inexpensive? Also, the buzzer/alarm part needs to be as small as possible. I appreciate all your help!

How can I get a loud alarm?

Ok so I need an alarm for my project, a very loud alarm. . . And I can't seem to get these dumb buzzer to output a decent sound. I have a lipo checker that uses these type of buzzers  and they are ear shattering. I tried putting the regular buzzers and the were no where near as loud. Also if I want to use the tone function on the arduino, how do i make the buzzer louder?

Distance Alarm?

Hello, I am interested in seeing if I can create some sort of alarm for my 10 year old son.  He has autism and I'm looking for something kind of like a house arrest ankle bracelet BUT i don't want it to track where he is. (Not at this point anyway).   For now i just want to see if I can make a distance alarm.  I would strap a bracelet to his ankle and I could carry the alarm unit in my pocket to If he got more than 100 feet from my device I would hear an alarm.  He has an issue with wondering away and the electronic monitoring companies want to charge hundreds of dollars to put a house arrest type monitor on him.  If i could make  something that would warn me when he starts to wonder that would be amazing! Can anyone point me in the correct direction? Thanks

Car Alarm

I just had an idea.... Someone needs to make a car alarm app for smart phones. It can use the microphone to listen for breaking glass, the speakerphone for playing pre-recorded messages (step away from the vehicle, the police have been called), the camera can sense movement inside the vehicle and the GPS can sense (and report) movement of the vehicle. All of this information can be sent in real time to the other phone that you carry with you. Installation is as easy as turning it on and tossing it in the seat! Compatible with any car! Battery backup! :)

Short range battery operated 2 part (door alarm type) distance sensor.

Hello all! I'm looking to design a range compact distance sensor that will sense 1-4 ft increments. If necessary i could modify a door alarm. id like to fab one or multiple if need be to sense the distances noted. I could utilize a buzzer or some way to record a voice that would alert to said distance. The battery voltage max is 4.2v dc and if it could be rechargeable that would be a plus. Any help on this would be greatly appreciated. Thanks!

An Alarm Clock Idea - No Lights, No Sound

I'm a pretty deep sleeper, and I don't wake up very fast in the mornings, which is bad since I ride the school bus to school. I set my alarm clock, with a high volume, but it still doesn't wake me very good. I've thought of trying to make an alarm that flashes a strobe light, something like a deaf person might use, but didn't think it would work very good. So, my idea now is to think of a way to make an alarm clock that gives pulsating shocks when it goes off. I have absolutely (well, 99%) no idea how to connect it up, nor how to produce the shocks. I'm thinking a shock with high voltage, but low current, like static electricity. I figure that should wake me. Do y'all have any ideas, or better suggestions? Also, do you think that the shocks (if usable) would cause any dangerous effects on my health? Thanks!

How to build a max distance alarm

I've been searching for an instructable that does that but couldn't find it. The basic idea is to put a small as possible tag to something(unpowered if possible) and have another small thing that can fit in your pocket. If the tag goes more than, say, 4,5 or 6 meters away your pocket box would warn you. I think its a great idea to protect from thieves but no idea on how could I build a device like that. Thanks

Just to make sure! 30A to charge battery?

Hey! I have an old home alarm system which is broken beyond repair. I just wanted to make sure if it is OK to charge the 12v battery at 2.1 or2.4 Ah with an ATX PSU at 30A? Will the battry just take 2A from it? If not I have the transformer that came with the Alarm, would that be safe to charge with? It's 12v BTW. Thanks. Never can be too careful. Also, I'm using it on a scanner light tube, this will be fine, yes? I have the starter, it is not a problem. It's weird though, when it is lit, you can pull out the ground on the light tube, not the starter and ut still stays lit. Weird. Thanks in advance!

How do I make an arduino into a personal alarm clock?

Dose anyone know how to build a super easy to use alarm clock using an arduino? I am prototyping different types alarm systems and trying to solve one person's specific problem with managing bed time. I welcome any: ideas, suggestions, hunches, guesses, or building plans. Just a few things: the clock has to use an arduino and it has to be portable. The reason why I'm building it myself instead of buying an alarm clock is that it needs to be utterly simple and have personal meaning to the user. I am open to it not having to use an arduino. It should be easy enough for a child 6 years old to use. They should be able to set the time and the alarm on their own.

PIR alarm somehow works WITHOUT PIR attached

So I was playing around with this instructable: https://www.instructables.com/id/DIY-Motion-Sensor-Alarm-System/ and it works great, I made it on a bread board and when I unplugged the PIR to switch a jumper, I noticed that the LED started acting as a sensor! That is, when I got close to the bread board, the LED would light up and the alarm would go off, it would stop when I moved my hand away and start again when I put my hand back... This may be a stupid question, but I am really curious how this works!

Small Radio-Activated Alarm / Key Finder

Hi Guys, I'm quite new to electronics (I'm a programmer by trade), but I'm a quick learner. I want to make a sort of radio Key-Finder (similar to something like this), but I'd like the "receiver" end to be rather small in size.  I'm trying to figure out how to go about starting something like this, but I would really appreciate some direction. Some questions: 1.)  Are there products that I can take apart and re-purpose for this? 2.)  Could something like this, for example, be a starting point for the radio "receiver" end? 3.)  I imagine that I would need at least a small battery (flat watch battery?), perhaps a small flat Piezeio-Electric buzzer (like one of these?) and the radio receiver. 4.)  Is this a project that needs something like an Arduino board to handle any logic? 5.)  Can I re-purpose a car alarm remote for the "remote" piece? Thanks for any thoughts and direction. Dan

Alarm using RTC.

Hi, I am new to arduino and RTC DS1307. I am trying to create an alarm using RTC and arduino. I have a buzzer that I have connected to arduinio and also I have connected RTC module to it. I am programming the arduino in such a way that whn the timer runs off, it produces a sound from the buzzer. I am trying to use Time.h and TimeAlarms.h libraries. I dnt know how can I make the timer buzz the buzzer.  This is the code I ve done so far.  #include #include "RTClib.h" #include #include ; RTC_DS1307 RTC; void setup () {     Serial.begin(57600);     pinMode(4, OUTPUT); // set a pin for buzzer output     Wire.begin();     RTC.begin();   if (! RTC.isrunning()) {     Serial.println("RTC is NOT running!");     // following line sets the RTC to the date & time this sketch was compiled     RTC.adjust(DateTime(__DATE__, __TIME__));   } } void loop () {       DateTime now = RTC.now();     Serial.print(now.year(), DEC);     Serial.print('/');     Serial.print(now.month(), DEC);     Serial.print('/');     Serial.print(now.day(), DEC);     Serial.print(' ');     Serial.print(now.hour(), DEC);     Serial.print(':');     Serial.print(now.minute(), DEC);     Serial.print(':');     Serial.print(now.second(), DEC);     Serial.println();     Serial.println();        delay(1000);             //Somthing sould come here to make the buzzer buzz     soundBuzzer(); //sounds the buzzer        buzz(4, 2500, 500); // buzz the buzzer on pin 4 at 2500Hz for 1000 milliseconds } // This is the function to make the buzzing void soundBuzzer(){   } //This is for the buzzer. It produces a beep. void buzz(int targetPin, long frequency, long length) {   long delayValue = 1000000/frequency/2; // calculate the delay value between transitions   //// 1 second's worth of microseconds, divided by the frequency, then split in half since   //// there are two phases to each cycle   long numCycles = frequency * length/ 1000; // calculate the number of cycles for proper timing   //// multiply frequency, which is really cycles per second, by the number of seconds to   //// get the total number of cycles to produce for (long i=0; i < numCycles; i++){ // for the calculated length of time...     digitalWrite(targetPin,HIGH); // write the buzzer pin high to push out the diaphram     delayMicroseconds(delayValue); // wait for the calculated delay value     digitalWrite(targetPin,LOW); // write the buzzer pin low to pull back the diaphram     delayMicroseconds(delayValue); // wait againf or the calculated delay value   } } I am really bad at programming so sorry for mistakes.

Hacking An Alarm Clock

My sister (yes, the one for whom I made earrings) wants me to modify an alarm clock to run a small electronic device when it goes off. Preliminary research has given me two methods:1) A digital clock with a 555 timer circuitIn this setup, a 555 timer circuit is used to translate the signal to an alarm speaker/piezo disk into a relay. When the clock goes off, the relay clicks, and any electrical device that is run through the relay has power.2) An analog clock with a transistor amplifierIn this version, the analog clock seems to just have a straight DC output to the alarm. The transistor is used to amplify the DC to drive the motor of a fire bell.Which of these would be easier to implement? The device I am supposed to use runs off of 3VDC, so I was just going to run the power line through the relay or through the transformer.

Newbie here, I want to activate buttons on a remote control when my alarm clock goes off.

Hey everyone!  I'm pretty new to all of this stuff, but I'm interested in connecting my alarm clock to my Arduino Uno, and connecting my Arduino Uno to various buttons on the remote for a remote-controlled, color-changing, screw-in LED light bulb, so that when the alarm goes off, the Arduino activates a series of buttons, turning the light on in various colors. My initial questions are the following, I'm most likely gonna need follow-up help later. 1. How exactly should I connect my alarm clock to the Arduino? I assume that there is a current produced somewhere when the alarm goes off, how do I "tap into" that, and how do I get my Arduino to sense the current? 2. I'm thinking (correct me if I'm wrong) that I need to connect each remote button to a pin on my Arduino and then turn on whatever pin I want to change the light bulb color. Do I just connect them using wires, or do I need something else, like resistors or another component? If I do need something else, how do I figure out what specs I need to have in said component? If it helps, below are links to the light bulb I'm planning to get and the alarm clock I have. Light Bulb Alarm Clock If there's any other info that it would be helpful for me to provide, let me know. Thank you so much.

Effective Way to Wake You Up

Getting up in the morning is not the easiest thing to do--but with the proper motivation, we all might be a little more inclined to hop out of bed. This alarm clock provides that: if you don't wake up, it will randomly dial someone from your cell phone's address book. An early morning call to your family, friends, or random person whose number you've got stored in there will guarantee that you have some awkward explaining to do.Link viaEngadget

Fire alarm!

This afternoon a couple of guys from the Mexican restaurant next door came up our stairs and asked how to get to the roof. They said something about a fire and smoke and it being urgent. We pointed them to our fire escape which has a ladder to the roof and then, for some reason, they lost interest and left. We were wondering if, you know, this was actually important or something when the fire engines started racing towards our building. So we looked out and two fire engines with ladders showed up along with 6 other vehicles and a total of about 25 firemen. It was on! The two ladders extended up to the top of the building where some smoke was coming out and a fireman climbed up to take a look. Fortunately, it didn't look too bad as none of the other firemen went up. Within about 15 minutes they started packing up and left. Just another day in downtown San Francisco.

He wondered if it would be possible to get alarm feedback from a usb key when a file is done saving. So I was thinking, could I somehow do something with a transistor or a relay on a usb cable, to sound an alarm for 1.5 seconds when the voltage turns to absolute zer0. I know how to solder and i did projects before, but never something like this, with this kind of tech. so tips and feedback could be welcome.
