Trill Ring is a one-axis circular slider that can detect up to 5 simultaneous touches as well as touch size. Trill Ring is the perfect controller for varying filters, sequencers, frequencies and more.

Want to add visual feedback and a button? Trill Ring is designed to fit within a , and fits an arcade button in the central hole. Trill Ring uses a Grove connector, and includes a Grove-to-male-pin cable so you can connect it to Bela, a microcontroller, or a breadboard and start prototyping straight away.

Dimensions: 52mm (outer diameter); 28mm (inner diameter)

About Trill

Trill is a family of touch sensors designed by Bela. , Trill sensors are designed to place the power of high-resolution touch sensing in the hands of artists, designers, musicians, and creative makers of all kinds.

For natural, beautiful touch sensing

Trill was inspired by the way we use our hands to interact with the world. Harnessing the power of capacitive touch sensing for interaction, Trill sensors come in a range of shapes, sizes and types to create a convenient way of integrating beautiful touch sensing into any interactive project.

Build beautiful, custom touch interfaces

Trill sensors can be used individually, or chained together to make even larger surfaces. You can use up to 8 of a single Trill type, or a network of different Trill sensors for a totally custom, perfectly crafted interface.

Trill sensors are also highly customisable. Not only can they be trimmed to size to fit exactly where they need to, but they can also be covered and fully embedded in a project, and calibrated in software for exactly the right responsiveness and sensitivity you need.

Designed for Bela, widely compatible

Though Trill touch sensors are designed to take advantage of low-latency processing, they are compatible with any system that suppports I2C communication such as , , and . Download the Trill library and example projects for Bela and other platforms on .
