From the MAKE Flickr photo pool Boss Sauce is working on an automated gardening system using Arduino – First mockup of Arduino-controlled garden, here switching a relay attached to a submersible pump to automatically water two plants. The “growduino” smart garden project will, um, grow to include more sensors and controls, but watering on a […]
Today we welcome the BlinkM programmable RGB LED into the Maker Shed! Have you wanted an LED that can fade from deep red to bright purple? Flash like a police light? Turn on with the subtle fade of an incandescent bulb? Flicker like a candle? That’s BlinkM. We’ve attached an ultra bright wide-angle RGB LED […]
Little-scale has another helpful mini how-to for those of you digging in with blue microcontroller It is often desirable to synchronise something like a homemade sequencing circuit or a Commodore 64 to MIDI clock signals. I thought I might share some generic Arduino skeleton code that could be used to synchronise many different types of […]
Flickr user Pianoman finds himself in an usually suspenseful situation with an Arduino project – So I built this little project for a friend. The idea is to take photos of a shuttle launch at down at Cape Canaveral. He has been doing this for a long time now… the routine goes like this: Accredited […]
Sparky the art-robot responds to air quality, movement, and touch by collapsing his body in relative amounts – indicating quality of environment. Sparking responds negatively to: carbon monoxide, cigarette smoke, alcohol, too much dark lighting, hitting and yelling. Any of the above factors (depending on severity) makes Sparky drop it’s head and tail, whimper, and […]
I turned an Arduino Protoshield into a digital-to-analog converter with only a few extra parts. It’s proved a lot of fun for audio experimentation and a great way to learn about what DACs do and how they do it. What’s DAC? Digital to analog converters, or DACs, are used to create varying voltage levels from […]
Limor of Adafruit Industries posted this video demonstrating how the Waveshield kit can turn Arduino into a sample-bending audio tool. Consider for a moment that potentiometer replaced by – oh let’s say – photocells or maybe a force-sensing resistor. If you’ll excuse me – I’ve got some experimentation to go do – Wave Shield for […]
