My wife and I have wanted to raise chickens(for the eggs) and we finally decided to do it this spring. I have read a lot about pastured chicken and wanted to create a mobile coop so that the chickens would not destroy the yard. I have a fairly decent sized yard for the burbs so […]

Step 1: What You’ll need A linux web-server with PHP, an arduino, a relay and some other components. Step 2: Upload your code to the arduino Upload the following code to your arduino: void setup(){ Serial.begin(9600); } void loop() { if (Serial.available() > 0) { char inByte = Serial.read(); if(inByte == ‘1’){ digitalWrite(13,HIGH); } else if(inByte == ‘0’){

This example shows you how to answer a HTTP request using an Ethernet shield. Specifically, it connects to pachube.com, a free datalogging site. The example requires that you set up a pachube.com account, as well as a pachube feed (for more information on setting up an input feed, please click here). Your Ethernet shield will

A “fan cart” is a roughly constant-force device used in introductory physics labs. It consists of a fan (usually a model airplane propeller on a brushed DC motor) mounted on top of a low-friction cart. Students use it to pretend they’re learning something about force, acceleration, energy, etc. If you’ve ever taken an introductory physics

In an earlier post I described an Arduino-controlled fan cart. The driver I used was an L293D quad half-H chip, because I had one handy and was out of simpler parts at the time. It’s always bugged me that I was just controlling speed on that cart, since it’s possible to control direction with an

My last theremin involved a small speaker. Now I’ve replaced the speaker with my PC, using processing to pick up the values from the SRF05 ultrasound sonar distance sensor and play different notes accordingly – which gives multiple possibilities and far better sounds. So to start with check out my previous theremin, the circuit is

So I’ve decided to build a robot using Arduino to control the sensors. Here’s my progress so far – I am hoping that my mistakes here and over the coming posts will guide people in more detail about what to avoid. Also I won’t provide a parts list until I have a working robot… The

Had a quick look round at turning a piezoelectric speaker in to a sensor that will detect a tap or knock. I also then had a search around for setting the output of a speaker to a different note. Combining this has given me a small basic Arduino drum machine and a headache to my

There is no better way to hide a covert device than to stick it inside a larger conspicuous device. That said… Essentially, this is a guide for making a data logging system for use with the breathalyzer microphone. To accomplish this, an Arduino and a Logomatic SD data logger are embedded into an old and

This instructable is part of the “Brickduino” series. [Brickduino 1. LED] – I expect that you did the Brickduino LED before you start with this instructable – Mainly this instructable is the same as the Brickduino LED! So if you want to skip all the steps that are the same than jump directly to step
