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 Neopixels ring, and fits an arcade button in the central hole. Trill Ring uses a QWIIC connector, and includes a QWIIC-to-male-pin cable so you can connect it to Bela, a microcontroller, or a breadboard and start prototyping straight away.

About Trill

Trill is a family of touch sensors that launched on Kickstarter in 2019. Inspired by the way we use our hands to interact with the world, Trill sensors use capacitive touch technology to make it easy to add high-resolution, natural touch interaction to your interactive projects. 

Trill was designed for Bela but is compatible with any platform that supports I2C communication, such as Arduino, Raspberry Pi, Teensy and more. Every Bela and Bela Mini system ships with a Trill library as well as lots of examples (including visualisations using our GUI integration). Libraries and examples for other platforms are available on our Github repo.
