Arduino is an open-source physical computing platform based on a simple I/O board and a development environment that implements the Processing/Wiring language.? Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer.?the open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). Arduino received an Honory Mention in the Digital Communities section of the 2006 Ars Electronica Prix.
Some new features available in Arduino diecimila, implemented in this Freeduino (Arduino compatible) board:
- AutoReset: It is possible to upload compiled sketch to the MCU without pressing the board reset button
- USB overcurrent protection: A resettable polyfuse protects the USB port from overcurrent and shortcut situations.
- New bootloader with 1 second delay
- Easy to solder board
The FT232RL chip is pre-soldered, eliminating the most difficult component to solder. The rest of the components are easy to solder through-hole. We also switched from metal film 1% resistors to standard resistors for easier value reading for novice users.
Freeduino (Arduino diecimila compatible) Assembly Instructions.
You only need a soldering iron, some solder, a multimeter and soldering skills.
Note: We replaced R7-R10 1k resistors with .33k ones for brighter LEDs.
