eTextile class with Lilypad

 First Day

Soft Circuits 101:

• power
• lights and switches
• resistors and Ohm's law

Rapid Protoyping techniques:

• fabric-friendly clips
• lilypad clips
• iron-on conductive fabric
• conductive tape, thread and etextile connections

Fabrics, and thread materials review

• Gold, silver and copper-plated weaves
• Silver and copper based threads
• Stainless steel based wool
• Conductive velcro
• Conductive polymer infused fabrics

Lunch Break (optional short UC Berkeley walking tour and group lunch)

Lilypad Introduction: what you can do with the fast software controlled switches built into the pins

Single digital pin tricks:

•  Proximity and Touch sensing
• PWM for audio, motor and light speed control 
• Serial communications (asynchronous)

Dual digital pin tricks

• powering circuits
• multiplexing resistive sensors
• H bridge direction control
• serial communcations (synchronous)
• SPI
• I2C

Analog pins and converting sensed signals into voltages:

•  using the built-in pull up resistors
• using current sources 
• potential divider
• signal conditioning

Second Day

Programming 101:

• The mechanics of creating and running programs on the Lilypad
• Programs are just recipes in shorthand (computer scientists like to use big words like abstraction, and data types)
• Sequencing, repeating, decision points
• Storing, recalling information
• Manipulating the pins

Lunchtime

Organizing programs

• functions
• libraries

Interactivity Programming

• Conditioning Information from Sensors
• Led arrays
• Sound and vibration
• Fabric motion synthesis
