It has a little lever with a wheel, and activates when something moves past it. You can also flip, the mode switch to make it turn off when the lever is pushed in.
These InnoBits are compatible with LittleBits and LEGO® making them modular and easily expandable. These would work great with the Meet Edison Robot.
Please note the modules are bigger than the LittleBits ones so they don't sit flush but the connectors do hook up.
