This package includes:
2x Sensor Holder
 
Sensor Holders are used with the Lego Technic Connector or the Lego Brick Connector to attach ultrasonic sensors to other pieces, such as Cube Connectors and L Connectors, in order to build sensor-based robotic machines and systems that combine Linkbot robots with Arduino boards. Sensor Holders may be used individually or snapped together to create a secure, top-and-bottom holder for ultrasonic sensors.
