This handout describes how to make a sparkling bracelet with the LilyTiny and two LEDs.

The paper version of the Codeable Objects lamp provides a quicker and less costly alternative to the wooden version, and is great for shorter workshops.

You can quickly create circuits on paper using copper tape, clear tape, and some simple electronics.

Codeable Objects is a library for Processing that allows anyone to design and construct an artifact using geometric computation and digital fabrication. This tutorial will show you how to use the library to make a laser cut lamp. The library allows you to customize the size, shape and decorative patterns of the lamp.

This handout for educators describes how to make a sparkling monster with the LilyTiny and two LEDs.

This tutorial explains how to do simple playback of short (~4 second), low-bitrate (8 KHz) audio samples from Arduino using only a speaker.

This tutorial explains how to use the TinyProgrammer, a small circuit board for loading code on the ATtiny45 and 85 microcontrollers (or other AVRs).

This tutorial shows you how to wire up an Arduino used as an ISP (programmer) to an ATtiny45 or ATtiny85. To find out how to write code for the microcontroller, see the the tutorial on programming an ATtiny using the Arduino 1.0.1 software (or the older version for Arduino 0022).

This tutorial shows you how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. These are small, cheap ($2-3) microcontrollers that are convenient for running simple programs.
