The Coquí is a circuit that allows you to 'hear' the readings from various sensors. Once the Coquí is assembled, you'll be able to 'hear' the conductivity of a solution, the temperature of a room, or the color of a pH test strip.
The design is named (onomatopeically) after the several species of small frogs which have a loud, distinctive call at night.
Demo Coqui applications
Building your own Coqui
- Coqui BBv1.0: a breadboarded version of the Coqui
Building Coqui sensors
- Making a conductivity probe from a bottle cap and two metal screws
