Introduction Are you looking to get your data gathering project hooked into the “Internet-of-Things”? Then check out data.sparkfun.com! It makes posting data to the web as easy as constructing a URL and POSTing it to a server. I wanted to create a quick project to test out SparkFun’s data logging service. Combining an Arduino, XBee […]

This Instructable shows you how to build a micro-controller based weather monitoring device. Built on the Arduino Uno board it can easily be extended and modified should you have additional sensors at hand. Main requirements: – Measure temperature (accuracy +/- 0,5 degree Kelvin) – Measure barometric air pressure (+/- 0,1 Pascal) – Display measured values […]

So about a year ago I decided that I wanted to get into AVR microcontrollers. After ordering an AVR pocket programmer from Sparkfun , I soon realized that it was too delicate to be sitting on a workbench full of wire clippings. I knew I needed a small enclosure to put it in, but couldn’t […]

The Arduino reads temperature from a MCP9700 temperature sensor IC and displays the temperature in the Arduino IDE serial monitor window. Also see the Arduino LCD thermometer tutorial (tutorial 14). Prerequisites Complete Tutorial 9: Using the Arduino Serial Port before attempting this tutorial. Components Besides an Arduino Uno board, USB cable, wire links and a […]

This is a clock designed to keep accurate time (independent of atomic or GPS), display local sunrise, sunset and solar noon, and also adjust itself for daylight savings time. I wanted the clock to be easy to use and be flexible. The setting functions are menu-driven, you set each parameter one digit at a time […]

I have wanted to build my own robot for awhile now. But after many tried and failed attempts, I was losing hope that may ever happen. I discovered that there wasn’t a small, robust, super easy to add-on to, robot that was within my budget to get. After hours of research and many robot kits later, i […]

ICStation team introduce you this APR9600 voice recording and playback system used in elevator based on the ICStation Mega2560 compatible with Arduino. It uses DC5V voltage to work. When you press the different keys, the loudspeaker will sound that which floor you arrive. This design uses a APR9600 voice chip as the core of the […]

In this Instructable, I will show you how to make an Arduino powered lamp that detects the colour under it and then attempts to emulate that colour. All using easy to find parts (most can be found in the Dollar store with the exception of the Arduino of course). It turns out that a colour […]

I have been working on this project for a while and whilst it is still under development I decided to write a short guide after several requests to do so. The dimmer uses an interrupt driven XL-Maxsonar EZ1 ultrasound range finder to measure the distance between the sensor and your hand. By moving your hand […]

Introduction The Rotary Emotiphone is a vintage rotary phone that tweets mood emoticons. It has a predefined list of 10 emoticons, each assigned to a digit, so that when you are happy / sad / drunk / etc., you pick up the handset and dial a mood. Could’ve gone for more complex messages using 2-digit […]
