[Paul] took the TVout library, the Wiichuck library and wrote it’s own 3D library. In this way he’s got a nunchuck controlled 3D shape on TV Movement in the nunchuck is detected by the arduino, then the cube is redrawn according to new angle of the controller. 3d wireframe library header and source. Code to […]
[DaveAK] shares his latest (uncompleted, never really complete, are they) CAN Shield. Now I understand that there are a few CAN implementations out there, but the more the merrier, right? This one uses the MCP2515/MCP2551 chips like most of them do. It has a switchable CS pin so that you can use other SPI shields […]
Arduino Forum User [Donster] posted a project about a Christmas Tree whose lights are lit by the word “Merry Christmas” on twitter: The basic idea is having the lights on the Christmas Tree turning on everytime someone tweets “Merry Christmas”. It’s still pretty much a prototype but you get the idea. Sometimes the live stream […]
Great Tutorial from TronixStuff about the less known Arduino AREF Pin. First: what is resolution? We measure resolution in the terms of the number of bits of resolution. For example, a 1-bit resolution would only allow two (two to the power of one) values – zero and one. A 2-bit resolution would allow four (two […]
Long time Arduino user and Arduino Forum Contributor [Grumpy_Mike] posted this morning it’s 10.000th post. Well with this post I reach the 10,000 mark, which is a lot of posts! It have been fun and I hope that some of them have been helpful. Apart from the odd odd character most people here have a […]
[Humberto Evans] and the team at Nerd Kits posted a nice Christmas project about making a xylophone and solenoids triggered by a microcontroller (they share the project). We’re unlikely to replicate this machining process but the solenoids are another story all together. Starting at about 3:30 you can learn about designing, building, and using […]

[Martin Nawrath] from Lab3, Cologne, made a nice ADC tutorial based on the 18bit LTC2400: If the resolution of the Arduino is not enough for your application you have to try it with a better ADC. The LTC2400 gives you a resolution of up to 24 bit at a datarate of 5 samples per […]

[Paul Bishop] shared code & pics about his project mixing a 8 bit FFT library found on the forum (in C) and the TvOut library. The first piece- data collection- is fairly standard. I use an electret microphone (which alone only produces a few mV output, far too low for our Arduino to use directly) […]
