Simple snap-on encoder wheels for TT gearbox motors. These injection-moulded plastic discs attach to the opposite end of the motor shaft from your wheel, letting you measure rotation speed using a photo interrupter sensor to count the ticks as the encoder spins.

An easy, low-cost way to add speed feedback to your TT motor-driven robot — although note that this single-slot design provides speed measurement only, not rotation direction.
