Touch Sensor Multiplexer for NXT / EV3
Including €0.01 for ecotax
This multiplexer for Lego Mindstorms touch sensors lets you connect up to 3 touch sensors using a single NXT port. Its simple design and small size allow you to insert it easily into all your robotic creations.
What is the difference between a multiplexer and a port splitter?
The port splitter does not distinguish sensors and motors connected to it. So, if you connect three contact sensors to the port splitter then you will not know what contact sensor was activated. On the contrary, the multiplexer distinguishes the sensors.
Programming the multiplexer with the NXT contact sensors
The touch sensor multiplexer for Lego Mindstorms NXT is programmable using RobotC. Click on the following image to download the RobotC driver.
