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.

Sean and I built this little Arduino project to change the number depending on the intensity of the light.

Workshop: "Meet the Arduino Microcontroller"
Museum Computer Network
MCN conference, Atlanta
November 2011
This photo was an 1st attempt to create an arduino mount that would be compliant with the contraptor hardware prototyping framework.
After a rough start getting the laptops to recognize the Sparkfun boards, participants in the Arduino 101 class learned to flash LED's - the first step into the world of embedded electronics.

Manufacturing Digital Art
In the 90s digital art was referring to immateriality, now the society has a more natural relationship with technologies, thus letting what is immaterial to become real, and experimenting new interaction processes between man and machine, that has completely become part of everyday life in the meantime. Manufacturing is also referring to digital art, where such equipment as Arduino and the explosive advent of 3D printers and devices for digital manufacturing led to integrate what is digital into what is real.

I got my arduino + accessories from ladyada.net / adafruit.com, and wanted to check that everything worked. At first I thought I bought a broken LCD screen - the pin numbers on the tutorial were different from those in the sample program. Once I figured that out everything worked, and now I just have to get on making the rest of this project...
The common cathode LED display array is connected in a matrix format, with each LED module sequentially scanned, with adjustment of anode drivers to produce the required digit.
For each scanned module, the Arduino sends 18 bits of data, 10-bits for the cathode driver and 8-bits for the anode, through 3x 74HC595 serial to parallel converters. Frame rate for the display is 100Hz.
The interface uses the high speed SPI hardware, with the software simply loading 3x 8-bit bytes and triggering the h/w transfer for each in turn. Data from the first 74HC595 is passed on to the 2nd after 8 clock cycles and then to the third after 8 more.
Pulse width modulation of nLED_ON allows for brightness control. If a column is selected for update to value that column will be brighter than the others. This gives a visual indication of how which decade of the digits will be changed when the rotary encoder is turned.
I found on a very early design that sending data to the display over the conventional serial bus caused the display to freeze and turn off whilst the serial comms was being actioned.
This implementation uses a custom interface that uses 3 pins and an interrupt routine. SER_IN_EN, SER_IN_CLK and SER_IN_DAT form this interface. It is similar to SPI but runs at a relatively low speed, reducing the flicker associated with updates.
The jumper "SIDE" is only fitted on the left hand bank. This pulls down the Arduino GPIO which the s/w reads at boot-up to determine if it needs to configure itself for the left hand mapping. If the jumper is not fitted the s/w configures itself for the right hand mapping.
Ilimit is an output from the Arduino to drive a red or green LED to indicate current limit (red) or voltage limit (green).

Made my first Arduino program, "Make an LED flash", and then Richard helped me make a "change frequency of LED flashing with an analog dial" because I am pretty electronics challenged. D:
