WeDo

WeDo is a LEGO Education control system in two generations: WeDo 1.0 (2009, USB hub) and WeDo 2.0 (2016, Bluetooth LE Smart Hub). It is programmed over USB or BLE rather than optically; its only optical component is an IR-based motion/distance sensor used for sensing.

Optical part = the motion/distance sensor

The "Motion Sensor" (a.k.a. distance/detection sensor) is IR-based: it emits infrared and measures the reflection to detect an object's presence/distance in front of it. Plus a tilt sensor (not optical).

This is sensing only; there is no optical programming or command channel. It is included for completeness as an optical-input LEGO device.

The hubs (lego-blockly supports WeDo 1.0/2.0) talk to the PC via USB or BLE. The IR here is only the proximity sensor, conceptually like the EV3 IR sensor's proximity mode but without a beacon or remote link.
