Measuring the consumption of a resource that has units by volume can be more tricky than it sounds. Use of resources such as water, gas, and even electricity is typically measured by gauges that determine either instantaneous flow rate or cumulative volume over time. Both techniques have problems: measuring flow rate at frequent intervals allows […]

As hard as it might be to believe, I had never built an electronic clock of any kind. I’ve always thought electronic clocks were passe and not worth the time to design and build one. In addition, I thought that all interesting electronic clocks designs had already been built so why bother building an also

A resolution of 8×8 pixels may not sound like enough for anything interesting, but with the right setup, it is possible to create beautiful, complex animations and even add some interactivity. In the next pages I will detail the steps needed to build the low-res display you see in the video below. Step 1: Parts
Low resolution display done right Continue Reading
This display is based on an 8×8 RGB LED Matrix. For testing purposes it was connected to a standard Arduino board (Diecimila) using 4 shift registers. After getting it to work I permatized it on a fabbed PCB. The shift registers are 8-bit wide and are easily interfaced with the SPI protocol. Pulse width modulation

This is a tutorial on how to program your DSLR camera to take photos photobooth-style. It’s a simple Arduino setup that allows you to take continuous photos with 3-second delay intervals. This was built for a college electronics project. A motion sensor detects motion in front of the camera, lights up and shows an LCD

This Instructable explains how to use a gas sensor with your Arduino. This lets your Arduino smell (and hence you program responses to) overall gas levels for a variety of nasties, including ethanol, methane, formaldehyde, and a bunch of other volatile organic compounds. My cost to make this actual device was under $100, including the

ArduSniffer This Instructable shows how to build a gas detector / indicator using an arduino. The finished product is USB powered and displays the amount of detected gas on a led display. In this design the reset button on the arduino is also working. This project will cost you between €25,- and €65,- depending on

Did you buy an arduino after seeing all the cool instructables and now you tired of just making LEDs blink? Are you envious of all the cool walking robots people are building but don’t have the experience or cash for all of those servos and expensive brackets? Here is your solution meet BoB the 4 servo mini

How to import the compiled Arduino IDE libraries into Atmel Studio 6.0 using a program written by Omar Francisco. This will allow you to use the feature rich programming environment of Atmel Studio to program the Arduino Uno. Other Arduino boards such as the Mega can also be used inside Atmel Studio but that is

I wanted to make it possible to control an arduino board from my phone. So that I could control other devices. the easiest way seemed to be using bluetooth. but when I received the parts needed I found it want quite as simple as I had hoped. And after looking on the Internet I didn’t
