Arduino polishes up its navigation skills via an inexpensive compass sensore component – A small digital compass based on hall effect is connected to an Arduino 10000 board. The logic in the board turns on and off leds depending on direction. There are 4 leds, one for each in N,S,W,E. When two leds are ON […]
Todbot makes an interesting suggestion Analog meters are hard to use in hardened environments. If you’re showing data from digital sources, why not use a digitally-controlled analog meter? laser cut acrylic meter face & needle, tiny 25mmx12mm $3 servo, and arduino. – Servos as meters on Flickr MotorShield for Arduino Kit
An Arduino, model bulldozer, servos, and sensors can be hacked together to make a sub-$100 robotics platform, appropriately named Ard-e. While certainly nowhere near as fancy as this Wall-E replica, the price is right and the Arduino’s got a huge body of pre-existing code for working with sensors that the aspiring roboticist can build upon. […]
From the MAKE Flickr photo pool Flickr user [fluxa] put an Arduino board to work outputting control voltage to a DIY SoundLab synthesizer. While the PC software has yet to be released, the Arduino code is pretty straightforward – using a pulse width modulated output through a simple resistor/capacitor filter. – CVAirSequencer Project on Flickr […]
Kyle writes – A friend of mine wanted a bitcrusher/samplerate reducer pedal for his guitar — I thought “you could probably do that with an Arduino”. The quality turned out surprisingly reasonable. I’ve released the code, which sets up the pins on an Arduino for doing 10-bit DSP at reasonable sample rates The design includes […]
Instead of waiting around for a faster Arduino to be released, Zach of NYCResistor is developing his own – I’m in the process of porting the Arduino environment to the atmega644 for a skunkworks project I’m working on. This chip is awesome because it has 4x the flash (64k vs 16k) it has 4x the […]
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 […]
