Trinket is the basis for a number of configurable sensors and a wireless bluetooth annunciator for building a customizable alarm system.

Is that meeting room occupied or not? Using just a few Adafruit parts centered around Trinket and a bi-color LED array, you can build a project which senses when a room is occupied and display the status outside the room. A red X tells you its occupied, a green square means its good to enter!

Making animals come alive with sound and motion is easy with Adafruit Trinket. This tutorial shows you how to animate an animal of your choice. You can be creative on what type of animal you make using paper, fabric, or even 3D printing.

A spin off a recent MAKE project Spooky Blinky Eyes, this adds pulsing, blinking LED eyes to your project. In a new twist, a photocell is added so the effect only displays when the lights are low.

The FLORA wearable controller has a all the muscle of a standard Arduino. This project combines Flora with the Adafruit VS1053 audio breakout and amplifier boards to simulate the sounds and light of Dr. Who's TARDIS time travel box. An IR remote can turn the sound off at your command.

Two analog meters and a real-time clock breakout are added to a Trinket, resulting in an analog clock that may be mounted in many different ways.

We're taking this project old school with a sound reactive Trinket-based Color Organ.

This project demonstrates use of the Maxbotix range finder and the Trinket. The distance is displayed on an LCD display connected via an Adafruit I2C backpack.

The Trinket mini microcontroller is perfect for displaying project information to devices using the I2C (2 wire) protocol. Here we show the project and code for a circuit which monitors the popular DHT series temperature and humidity sensors.

Trinket and Gemma are perfect for small projects needing to receive some external event, triggering your own defined output. This project uses the Adafruit IR Sensor to first receive IR commands from a remote, then to use those codes in controlling a project of your own.

Shrink the Arduino theremin music project to Trinket and Gemma size. Make music based on the light intensity of a Cadmium Sulfide (CdS) photocell.

Learning to control servos with the Trinket mini microcontroller is a bit different from other Arduinos. This guide will walk you through the process of controlling a servo with a potentiometer as the input

This guide takes you step-by-step through the process of installing Arduino libraries on Windows, Mac OSX and Linux platforms.
