OLE workshop – Cairo

October 16- 30, 2009
Venue: The Rooftop Studio
Partcipants: 24
Instructors: Alex Posada, Sergi Lario
During the two weeks of workshop a space of reflection, investigation and collaborative work developed in a context of production, encounter, dialogues and collective learning where several tutors exert of technical advisers of the artists and work groups who develop each one of the proposals.The platforms taught are all open – software and hardware.Contents:
- Introduction to electronics and microcontrollers concepts – Using Sensors – Control of Video and Audio – Work on projects suggested by the participants

Duration: 15 days, including open seminars and demonstration of resulting works
Day 1: Introduction to Electronics and Arduino
- Breadboard.
- Electronic components description.
- Basic electronic laws.
- Introduction to Arduino hardware and microcontrollers .
- Programming Arduino board.
Install Arduino software
- Connect Arduino to computer.
- Program simple blink led example.
(Objective: Introduction to electronics and microcontrollers concepts)
Day 2: Introduction to Arduino software
- Description of the basic instructions (reference)
- Theory of serial protocol.
- Concept of analog and digital. Sampling and bitrate.
- Reading buttons and analog values.
- Using leds like visualizer.
- Sending data with the serial port.
(Objective: Comprension of the Arduino software and basic examples)
Day 3: Sensors and actuators
- Explain different sensor technologies. (light, force, acceleration, infrared, ultrasonic, etc.).
- Explain different actuators technologies. (Motors, Servos, lights, solenoids, relays, etc.).
- Reading different kind of sensors.
- Simple examples for control of different kinds of motors using extra electronics.
- Controlling complex actuators, high voltage, motion, etc.
(Objective: Comprension of basic sensors and actuators – Phisical computing tools)
Day 4: Arduino vs. Pure Data
- Simple protocol strategies to send/recieve data to/from computer.
- How to send data from sensors to PD.
- How to control actuators from PD.
- Basic examples and communication between Ardunio and PD.
- Controlling Arduino from Pure Data.
- Controlling a computer from Arduino.
Day 5-14: Thematic Working Groups (Practice)
The participants will form groups and work on projects proposed by themselves.

Presented by: The workshop is organized by Medrar (Cairo) and Hangar (Spain) Instruction and supervision during the workshop leaded by:

Sergi Lario
Programmer, visual experimenter, engineer in computer systems and technical development of applications. Escaping from the commercial world he has put his deep technical skills to the service of digital arts – giving workshops on interactive video, performing visuals in numerous spaces in Spain and collaborating in Pure Data development – notably the collection of Pdvjtools.

Alex Posada
Electronic engineer, musician and digital artist, he centers his work on the search for new forms of interaction with technology. He currently directs the Interaction Lab in Hangar, Barcelona where he has developed numerous projects for artists.


With Carlos Martinez he has the group Neuronoise (http://neuronoise.org), creating live shows and installations that combine sound, image and interactivity.
