How often do you ever forget to feed your fish? Well, for me I don’t forget that much. I just couldn’t go out town for a couple of days and also be ridiculous if I should bring my tank along. When I won a Sparkfun RedBoard from Sparkfun Analogy Contest, this was the first project […]

Almost inevitably, when I try to climb the same route I’ll forget exactly what sequence of holds they used and end up following a slightly different path. Even when I remember exactly which course to follow, I’ll still wonder whether I’m doing it as quickly as the previous climber. Yes, I know that skill in

This was originally going to be a tutorial on how to hook up a pumpkin to the internet so that the lights inside it could be controlled via twitter, text message, motion or more. To get started I carved a pumpkin for the first time in 20 years. Needless to say I was proud of

Description This little project makes a great ornament to hang in your window at Christmas time. It is a 20″ wide star with 50 “neopixel” leds around the perimeter. Each led is individually addressable and it is controlled by an arduino device which can be programmed to sequence the leds in various patterns. Depending on

Using the Mouse library, you can controls a computer’s onscreen cursor with an Arduino Leonardo, Micro, or Due. This particular example uses a pushbutton to turn on and off mouse control with a joystick. Cursor movement from the Arduino is always relative. So every time the analog input is read, the cursor’s position is updated

So, looking at these Kaoss pads and alike hardware, I found that there is hardly any point in this device being so expensive, when you just want to use it as MIDI controller. Going through my parts bin, I found a Synaptics touchpad from an old laptop and figured this should just work as a replacement.

Quick and simple start guide for using and exploring the Flame Sensor module with an Arduino. The model in the example I am using is from Deal Extreme [DX] and can be found HERE. (The instructable for the Rain Sensor is now available!) Materials needed: Flame Sensor (model with an analog out) Male to Female

This sketch uses the Serial.parseInt() function to locate values separated by a non-alphanumeric character. Often people use a comma to indicate different pieces of information (this format is commonly referred to as comma-separated-values), but other characters like a space or a period will work too. The values are parsed into ints and used to determine the color

Lighthouses have been guiding boats to safety for thousands of years. One of the earliest and most notable of these was the Pharos of Alexandria. This huge structure stood for nearly two thousand years. When deciding on a lego project, I wanted to build something practical, yet at the same time fun. Although I won’t
