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 […]
Jimmie is taking pre-orders for his “Open Heart” Arduino LED matrix kit. He’s also posted a convenient flash-based designer for creating your own charlie-plexed animations. – Open Heart kit Related: HOW TO – Arduino charliplexed heart
Ever wondered how the Arduino would fair as a keyboard synthesizer? Wonder no more – the Pocket Piano kit from Critter and Guitari proves Arduino can sine and saw quite well. Features include – 25 keys and multiplexer circuitry 4 potentiometers, 1 controls output level Microchip MCP4921 12 bit SPI DAC Passive low pass output […]
Just when you thought you had them all, the Arduino mutates yet again – The new Arduino Nano is the smallest and most versatile Arduino board yet. Designed and manufactured by US-based Gravitech, it has all the functionality of an Arduino Diecimila in a compact, breadboard-ready design. The Nano includes an ATmega168 microcontroller (w/ bootloader), […]
Dino shares some details on his hacking methodology for an Ardueeno-toy-bot. This is a Rumble Robot I’m hacking and turning into an autonomous exploration robot with the Arduion as it’s central controller. This is stage one, getting the motors to drive it. Looks like fun!

I just got a firsthand look at the Arduino Pocket Piano from Critter & Guitari. Looks like much future fun – expect to see more on it soon.
