Dhananjay Gadre wrote in from New Delhi with news of “GuGaplexing”, an update to the tried and true technique of Charlieplexing. GuGaplexing introduces a set of transistors into the mix to double the number of LEDs you can address: The transistor pairs are so arranged that they provide an out of Vcc/2 at the output […]
Here’s a helpful library that allows one to add simple IR control to projects The library implements the NEC IR protocol, so set up the universal remote for any NEC device (TV, DVD, VCR, …) and the 32-bit codes should be received. The example sketch provided just prints out IR codes as they’re received, so […]
The Drum Master project uses sensor filter circuits with the Arduino platform and sends the data over USB for sample playback – The Drum Master system is actually comprised of two parts. The hardware brain module (containing the Arduino microcontroller and a collection of circuits to assist in obtaining the sensor information) is called the […]
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 […]
