Typing text in an SSH session on a laptop over wifi to a Raspberry Pi on a wired LAN which then sends the text to an Arduino over USB - the Arduino then translates the text into Morse code beeps and light flashes.

An Arduino controlled vehicle - still to be enhanced with a Bluetooth remote control (module already shown in the "parts view") - uses an L293 motor controler chip - see www.me.umn.edu/courses/me2011/robot/technotes/L293/L293.html

You can see in the lower right corner of the board that there is an extra max232 and RS232 to USB adaptor. It's used for debugging as I don't have to quit the serial terminal when uploads programs to the microcontroller.
yes, trip to maplins this lunchtime, back with a boatload of electronics bits and bobs for my basic foray into physical computing.
3 LEDs, chasing a la cylon/knight-rider, but "ebbing and flowing" (i.e. slowing down and speeding up).
and yes, before anybody reminds me: i know my choice of jump wire colours leaves a lot to be desired...should get myself a few more red and black ones.
Arduino Academy, a 3-day summer programme for students in New Zealand, 7-9 July 2014. Catalyst IT was the organizer.
ISP ATtiny85 shield for Arduino.
The basic connection instructions is widely available through the web.
We taught a workshop on how to create interactive art with the Arduino platform at the Mill Valley Library on October 24, 2015.
We showed 9 students how to make lights blink, sounds play, motors move, and how to add more color with neopixel LEDs, as described in this online guide we created for the workshop:
At the end of the workshop, we asked participants if they would like to this again, and the answer was a resounding yes! Participants told us they learned a lot from this workshop and would not only come back for future workshops, but also recommend this program to their friends.
Instructors for this workshop were Donald Day and Fabrice Florin, with support from Natalie and Jean Bolte. We are all members of Pataphysical Studios, the art collective behind the ‘Pataphysical Slot Machine’, our poetic oracle.
Come visit the exhibit this month! We’re open every Saturday and Sunday in October, from 1 to 5pm, in the downstairs conference room of the Mill Valley Library.
Special thanks to the Mill Valley Library and the Friends of the Library for making these workshops possible — especially Kristen Clarke, who helped us get the Arduino parts and set up for the workshop.

These are some pictures of the liquidware geoshield for the arduino. The source code and schematics are available at www.liquidware.com
New Arduino-compatible Freeduino's. Borrowed some of the lables from the UNO, but kept with Duemilanove design standard. Can't complain about the classic (with upgrades)!
