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 designed by Bela. Launched in 2019 on Kickstarter, 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 Bela’s low-latency processing, they are compatible with any system that suppports I2C communication such as Arduino, Teensy, and Raspberry Pi.
