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 ...

Arduino Based Auto Timer

The Need: Last week around at work I had another usual un-usual  problem to face with.  Having to make lots of mechanisms n components to work with-in seconds or fracs at times I kind-of knew this was always coming. And invariably so my poor mind couldn't think of anything but Arduino for a handy solution that should be compact, flexible, highly customizable, rugged and most importantly easier to work aroun ...

Arduino Color Sensor

Here we will be learning how to make a color sensor. my model consists of three cardboard compartments containing an LED - one red, one blue, and one green - and an OP550B phototransistor. The LED's shine simultaneously on a solid colored card. The phototransistors are connected to an Arduino Uno, which converts the relative amounts of measured reflected light of each color into RGB components which are use ...

Carduino- A simple Arduino robotics platform with its own library

This is, as the title says, an Arduino-based robotics platform, with its own library. The "standard" model comes with two back motors, two omni-wheels in the front, and a distance sensor mounted on the front. It also has breadboard space on top for adding whatever you want. It is intended to be autonomous, but one can make it remote controlled if they really want to. This instructable will teach how to buil ...

Building a semi Smart, DIY boat with Arduino and some other sensors

I based this off of this really nice instructables.com post for building a water bottle boat, with some additions for obstacle avoidance and light-guided control. I used Arduino as a microcontroller, an ultrasonic sensor in the front, a few simple switches on the side of the boat, and a few light sensors on either side.  See here for a few more photos or here for a pdf step by step. This simple little float ...

Remote controlled webcam using Arduino

Web-enable your interactive sensors over desktop, smartphone and tablet devices. This tutorial describes in detail how to use the free SensorMonkey service to remotely control a pan and tilt webcam attached to an Arduino using nothing more than a simple webpage. The webpage can be viewed on any desktop, smartphone or tablet device with a compatible web-browser. I use the jQuery UI library to provide interac ...

Bike Speedometer using an Arduino

Monitor your road speed using the Arduino. This project uses a magnetic switch (also called a reed switch) to measure the speed of one of the bike's wheels.  The Arduino calculates the mph, and send this information out to the LCD screen on the handlebars as you ride.  It is compatible with any kind of bike/wheel, simply enter the radius of the wheel in the firmware to calibrate the device for your setup. P ...

Waveform Generator using an Arduino

Waveform generators (also called function generators) are useful for testing and debugging circuits.  I often use them to test the frequency response of electronics components like op amp and sensors.  This waveform generator is powered by an Arduino.  It outputs four waveshapes: sine, triangle, pulse, and saw, each waveshape ranges in frequency from 1Hz-50kHz.  The frequency, pulse width, and overall ampli ...

LED Matrix with Game Controller using an Arduino

This project was built for my introductory electronics class at the University of Waterloo in Canada.  This was my first introduction to electronics and therefore, my first project. Follow these steps to build a 16 x 16 LED array with a wall (different colored LED on the border), powered by an Arduino Mega 2560.  I have also included the construction details of a game controller. This project is ideal for a ...

Sous-vide Arduino Shield

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC Sous-vide (/suːˈviːd/; French for "under vacuum")[1] is a method of cooking food sealed in airtight plastic bags in a water bath for a long time—72 hours in some cases—at an accurately determined temperature much lower than normally used for cooking, typically around 60 °C (140 °F). The intention is to cook the item evenly, not ...

Audio Output using an Arduino

Generate sound or output analog voltages with an Arduino.  This Instructable will show you how to set up a really basic digital to analog converter so you can start generating analog waves of all shapes and sizes from a few digital pins on an Arduino.  (This article is a companion to another Instructable I've written about sending audio into an Arduino, find that here) Some ideas that come to mind: sample b ...
