The Lightuino is an Arduino-compatible circuit board that lets you easily drive lots of LEDs. You’ve got 70 independent channels to play with, and can stack 3-4 LEDs in each channel.
It works great for model train lighting, LED coffee tables, LED art, and indicator lighting (such as lighting locations on a map).
No resistors necessary! The Lightuino powers the LEDs using a constant-current driver chip, so you get a consistent light intensity and you don’t have to deal with those pesky resistors.
It is Arduino-shield compatible with “stackable” headers. For example, you can put this on top of an Arduino and then put a shield on top of it! You can even stack multiple Lightuinos to light more LEDs.
The Lightuino can also be used to drive servos, DC motors, relays, etc, with minimal additional components (resistors, diodes and transistors)
Open Source Project :Driver library, hardware schematic, and Arduino “sketches” are fully open-source and available.
Project videos :Sorry I’m still figuring out how to make good videos :-)
NOTE: To use this board, you need to be familiar with programming in the Arduino environment, or willing to learn. You also need a USB-to-serial (FTDI) cable to program it from a USB port. These cables are commonly required by Arduino clones (google search “FTDI cable”).
WARNING: This is a DIY item. It is a raw, unenclosed circuit board. The buyer assumes all risk and responsibilities associated with using and modifying this device.
Strongly recommended items:
2 40 pin IDE cables to connect to the board.
Wall-wart transformer 7.5 to 20 volts, 2.1mm jack. The one you use with your Arduino is fine (note, it is possible to use power from the USB cable but there is not enough power in the USB to drive the full 70 LEDs at 15mA).
LEDs. Your typical 5-20mA LEDs work great. Any color :-).
For RGB LEDs buy “common anode”.
Soldering iron or breadboard to connect the LEDs up.
