Home Automation using Arduino and MATLAB

n present time home office appliance controlling is common thing.  Today for controlling home/offices appliances, machineries in companies/industries uses different types of automation systems like DTMF controlled, GSM controlled and many others. So here this project is made for interfacing MATLAB (Graphic User Interfacing) and Home/office/industries automation using Arduino and MATLAB. Here MATLAB is inter ...

Secret Knock Detecting Door Lock using Arduino

Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock. This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. If the precision is turned all the way up it can even detect people apart, even if they give the same knock! (Though this does trigger a lot of false negatives, which is no fun if you're in a hurr ...

The Soil Temperature Sensor using arduino

You are building a soil temperature sensor. We need a waterproof thermometer that we can burry in the soil. The sensor is made up of a small circuit enclosed in a piece of heat shrink (to waterproof it). Supplies: (see the parts page) an LM335 temperature sensor a 33K and a 56K resistor a short piece of glue-lined heat-shrink tubing soldering iron and solder lead wires The circuit for the actual sensor This ...

Sleep Tracking using an Arduino

Background and motivation This project was motivated by two things: my almost complete inability to get out of bed in the morning, and my fondness for recording data from routine activities and making graphs with that data. My main problem with waking up in the morning is that feeling of grogginess along with an intense desire to sleep more. However, I've noticed that sleeping without an alarm clock, and ju ...

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 ...

Lego Spybotics with Arduino

A friend gave me his old Lego Spybotics robot, however, the programming environment that goes along with it is a bit too orientated to the younger user. So why not control it using an Arduino? Step 1: Open up! In order to get this robot moving, we need to borrow its motors. There are two DC motors in the robot. This is great, because we can control them independently, allowing forward, backwards and turning ...

The Soil Moisture Sensor using arduino

You are building a cheap soil moisture sensor so the brain can read the amount of moisture in the soil. The version we are building is very low tech, but it is also very cheap and easy to build. It consists of a block of packing foam with a couple of wires shoved into it. And the great thing is that it's possible to use reclaimed materials in much of it's construction. If you cruise around the web, you will ...

Arduino Automatic Watering System For Plants Sprinkler

Last month, Elecrow have left from the original office and moved to a new office. We will miss our original office where we worked so hard for more than two years, we will miss everything here, the desks, the windows, and those potted plants, that we cared for more than two years with our neighbor. Our neighbor, a design team, led by a man named Kimi, we had so many memories together in the difficult early ...

The iButton garage-door opener using an Arduino

I've made an iButton garagedoor opener and logger. On a Dutch (kind of) eBay (www.marktplaats.nl) I found some iButtons and readers very cheap. I had no idea what to do with them, but I bought them anyway. My garage opens with a push on a button, so it must be possible to get that working with the iButton. I also found some really cheap (0,50 euro) displays, so it would be nice if I also can make a screen t ...
