This looks pretty interesting. Just got this info from Parallax PR: The CO Gas Sensor Module is designed to allow a microcontroller to determine when a preset CO gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires two I/O pins from the host […]
Xander Hudson, aka Synoptic Labs, posted this cool heart card project to the MAKE Flickr pool. He writes: This year I gave my sweetheart a LED valentines day card. The LEDs were animated with a pulse harmonic tuned to my own heartbeat. (sappy, yeah I know, but she makes me feel sappy). Incorporates 1 AVR […]
Dave Prochnow writes on PopSci: Every AVR programmer worth her weight in ATmegas knows about the AVR Butterfly–a ridiculously low cost ATmega169 demonstration and evaluation kit. Lamenting the lack of such a kit for the ATmega168 drove me to design my own demo/eval kit for the Arduino microcontroller family. This project became a compulsion that […]
The Arduino open-source microcontroller platform can be programmed and equipped to perform a nearly endless list of functions. It’s likely the best all-around centerpiece to a modern electronics project. But one of the tasks Arduino is best used for is straight-up fun – the open design means there’s an Arduino board suitable for almost any […]
HOW TO – Make a plush “irradiated sirloin”… Microcontroller night light illuminates meaty issues By Rebecca Stern – Faced with an assignment to make a plush night light, I thought, “Why light?” and brainstormed reasons for a stuffed toy to light up. In a glowworm toy, for instance, the light mimics nature. I’d been reading […]
Evil Mad Scientist Labs introduces the Mignonette AVR gaming platform, developed by Rolf van Widenfelt, Mitch Altman, and EMS’ own Windell Oskay – The Mignonette is designed to be easy to assemble, and uses a rather minimal set of components– the AVR microcontroller, the LED display, and a pair of ULN2003A transistor driver chips for […]
Linus Akesson and friends have created the “Craft” demo – using an ATmega88 to generate 4 channels of 8-bit sound and 3D graphics. Timing is crucial: One display line takes 24 μs, and is followed by a 7.75 μs break called the horizontal blanking period. After 480 such lines, there’s a longer break (1428.75 μs, […]
