The Arduino Dev Board [Sticky]

Arduino is an open-source physical computing platform based on a simple i/o board, and a development environment for writing Arduino software.

Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other outputs. Arduino projects can be stand-alone, or they can be communicate with software running on your computer (e.g. Flash, Processing, MaxMSP.)

Driving a WS2811 RGB LED Strip with an Arduino

I recently purchased a WS2811 RGB LED strip for PC case modding purposes. I will be making an ATMega-based controller for it, so I decided to use an Arduino for testing and prototyping.

I found two libraries capable of driving this strip:

DFRobot LCD Keypad Shield and the LiquidCrystal Library

The DFRobot LCD Keypad Shield is found at and various other retailers (Robotshop, etc)

To use this shield with the LiquidCrystal library, use this define:

QuahogCon 2010: My Freeduino (From AlphaOne)

QuahogCon 2010: My Freeduino (From AlphaOne)

This is my new Freeduino, which I purchased as a kit from the fine folks at the AlphaOne Hackerspace table at QuahogCon 2010. Stuff: Arduino Shield, Breadboarding Supplies, etc Stuff: Arduino Shield, Breadboarding Supplies, etc

My latest order.

For PIC programming:
BOB-00193 (1): Adapter board for Microchip ICD and ICD2

For (hopefully) adding some IR functionality to my QuahogCon badge:
COM-09349 (4): Infrared LED - 950nm

For parts:
DEV-00348 (2): Olimex Carrier Board for OKI ML67Q5003

Arduino: Barcode Scanner (Work In Progress)

Ok, here I have a Symbol LT-1780 handheld barcode scanner. It has an RJ-45 cable with a 9-pin end (Not RS-232). I took an old RS-232 plug and put that on the end of the cable, and used that to wire it up to the Arduino.

Pics Soon.
