I have been researching a project which will help me with my understanding of electronics, networking, and programming.  I decided to build an online thermometer which could be used in applications that need temperature monitoring.  I currently work in a lab environment where I test, troubleshoot, and calibrate equipment which is installed in nuclear power plants […]

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 […]

Sometimes when you’re testing a sensor or debugging a value in an Arduino project, you want to see something other than numbers flying by in the Serial Monitor. However, you want to get the sensor working quickly, and you don’t want to take the time to write code to graph it or display it in […]

The next board I want to show you is the ADJD-S371 Color Light Sensor Evaluation Board from sparkfun. It emits light and analyses the reflected color spectrum. The board can be controlled via I2C. The sleep and xclk pins were not used in this example. I found a really nice tutorial describing how to connect […]

What if making an Arduino, or wiring up an Arduino was as easy as printing one out? In this tutorial we printed our own Arduino Pro Mini board using a pen plotter and the Electroninks Circuit Scribe (a rollerball pen with highly conductive ink). Within 15 minutes we printed the board, placed components down with […]

I was always impressed by the Daft Punk Coffee Table.  Being able to light up a bunch of LEDs and flash them in patterns has so many applications.  It was one of the reasons why I bought an Arduino seeing how it could control a matrix of LED lights.This is my attempt at building the […]

INTRODUCTION This manual will show you how to use each of the components in the kit, and give you software Sketch examples for each one. Then you can combine some components to make examples of Automatic Systems such as a lighting controller.   You’re probably here because you’re interested in MAKING things with Arduino. The […]

I don’t get up at the same time every day, so I thought it’d be nice to have an alarm clock that would drag me out of bed at different times on different days. That was the initial idea: things got out of hand, of course, and this is the result. What it does: 1) […]

This is a DIY variable resistor I created as an interface for live performance– like a stomp box. I designed it as a project my audio students could build with materials we already have in the classroom. The result is a variable resistor that can be triggered with just a little pressure from hands or […]

I’ve had a cuecat barcode scanner sitting around for over 10 years. Basically it connects to a PS2 port (apparently there is a USB version) like a keyboard and spits out a barcode when scanned. Nice!. The annoying thing is that it is “encrypted”. What I set out to do is; – unencrypt the barcode […]
