Human Body Infrared Smoke Temperature Alarm System with Arduino

Web site: http://www.instructables.com/id/Human-Body-Infrared-Smoke-Temperature-Alarm-System/ Project Summary: The Human Body Infrared Smoke Temperature Alarm System works under the DC 5v voltage and uses the DH11 Temperature Module to detect the room temperature. When the module detects the temperature is higher than the maximum, the buzzer alarms and the red LED lights. When the MQ2 Smoke Sensor detects t ...

Alarm Clock with Tetris to Prove You’re Awake using Arduino

This is an Arduino powered alarm clock that after hitting snooze twice the alarm will not cancel until the user has cleared 4 lines in the game Tetris. You physically turn the clock sideways, so the screen is vertical, to play Tetris.  It's never fun to wake up in the morning but playing a little Tetris is at least somewhat enjoyable and quite effective. Feel free to vote for me in the microcontriller conte ...

Open Source Hearing Impaired Alarm Clock using Arduino

Activities of daily living (ADL) are self-care activities that are usually taken for granted, since as the name implies they are performed on a daily basis. If you have ever ended up in a cast, or on crutches you can empathize how menial daily activities can suddenly be very difficult to perform. Waking up in the morning and maintaining a schedule is obviously an important ADL, and for those with hearing im ...

Cat Repelling PIR motion sensor (covert) speaker box alarm using Arduino

This is a PIR motion sensor device that works with the arduino uno. In order to make it covert enough to be placed in multiple settings and portable enough to fit most places, I decided to make the case for it appear as a speaker. The inspiration for this project: My cat is a jerk. One of his favorite things to do is to alarm me that he is hungry every morning at 4am by sitting on my dresser and knocking ra ...

Arduino Led Alarm Clock

This is a project that I have been working on a few months now and I have completed its build very lately.  The main processor used in this project is an Arduino MEGA 2560 which is interfaced with a real time clock called the DS 1307 chip (which gives you the time and date). Both Red and Blue LED Displays are driven using NPN transistors ( I used 2N5551 NPN transistors).  The bases of these transistors are ...

Arduino Board Sound Alarm

I’ve just completed my second Arduino project, a sound level detector which sets off an “alarm” when there’s the sound level is to high for too long.  I built it for use in a school that wants to provide visual feedback to students when they are being too loud.  The “alarm” is a string of flashing LEDs that’s controlled by an IR-remote, which I reverse engineered using the the arduino itself and the excelle ...

A laundry alarm for the hearing impaired and everyone else using Arduino

This Arduino based project was designed to solve a recurring problem for my hearing impaired wife. Our laundry room is located remotely from our living area.  If our laundry has finished washing and is not removed in time, it can sour or even get moldy.   If our laundry has finished drying and is not removed promptly, then severe wrinkling occurs.   My solution is to sense when the washer or dryer has turne ...

The useless alarmed Coke can using Arduino

Hi all! This is the most useless project in the world! It consist in a Coke can attached to an Arduino trough a coaxial cable and two resistors that make a sound when an hand is near it. Step 1: Materials and Tools For make that I've used: Materials: -1x Arduino Uno Board (or equivalent) -1x 270kOhm resistor -1x 10kOhm resistor -1x alligator clip (not in the photo) - a piece of coaxial cable - a short wire ...

Turing Alarm for Arduino

NOTE: This Instructable is currently incomplete. I will finish it before September 19.  I started this project after seeing Nick Johnson's Turing Alarm clock. I found that the PIC chip he used was a little too advanced for me, so I decided to use the Arduino microcontroller. The original project by Nick Johnson can be found on his blog here . All credits for the idea goes to Nick. The turing alarm forces yo ...

Arduino Binary Alarm Clock

This Instructable will show you how to build an binary alarm clock, with a touch sensor snooze button. This is my first instructable and my first real arduino project, I hope you like it! I bought an arduino a while back and I think it's really nice, but I haven't really done anything useful with it yet, so now I thought it was time to make a bigger project. I decided to do an alarm clock since my old one i ...

Bubble Alarm Clock Makes Waking Up Fun using Arduino

Waking up to a buzzing alarm clock sucks. I'm one of those people who doesn't like to wake up before the sun is out (or has been out for many hours). So what better way to make waking up fun than having a bubble party in bed! Using an arduino and a commonly available bubble machine toy, you too can wake up to the joy of bubbles. Step 1: Tools & Materials The Parts (you can definitely substitute for stuf ...
