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! In the Maker Store: Arduino Diecimila
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.
Another quick & easy option for those getting started with the popular micro – Little-Scale posted a quick rundown on using a solar cell for Arduino sensory applications. The solar panel used in this example was rated at 2V and 25mA. Do not use a solar panel rated in excess of 5V. Doing so may […]
Here’s a how-to regarding the detection of volatile organic compounds using Arduino and a TGS2620 sensor – This lets your Arduino smell (and hence you program responses to) overall gas levels for a variety of nasties, including ethanol, methane, formaldehyde, and a bunch of other volatile organic compounds. No explanation as to how refraining from […]
A user on the Arduino forums built this high-speed photo flash trigger – I used Arduino to build a trigger for my camera’s flash. It turned out to work really well! The write up includes an explanation of how camera triggers work and the benefits of using Arduino. One benefit of using a microcontroller like […]
