Trill Bar is a multitouch slider that can detect up to five simultaneous touches along one axis. As well as sensing finger positions, this sensor also detects touch size for each finger, allowing it to act like a pressure sensor. Trill Bar 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: 112mm x 22mm
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.
