Discovery Set
(read "21 to 1"), one revolution of the shaft coming out of the gearbox,
corresponds to 21 x 3 = 63 encoder pulses.

XS Motor

The XS motor is an electric motor, exactly as long and high as a
fischertechnik building block. In addition, it is very light. This means, you
can install it at points too small for the big motors.
Both gearboxes included in the construction set fit perfectly on the XS
motor.
The XS motor is designed for a supply voltage of 9 volts and a maximum
current of 0.3 amperes.

LEDs

Two LEDs are contained in the construction set. They can be used in a
variety of ways. For example as signal lights in a traffic light, as flashing
lights on a robot or for better illumination of an image supplied by the
camera also provided in the construction set.
The LEDs are designed for a voltage of 9 volts and consume
approximately 0.01 amperes of current.
Caution!
When connecting LEDs to the power supply, always pay particular
attention to correct polarity. Connect the positive pole to the red
marking on the LED.

Lens Tip Lamp

This incandescent bulb contains a lens to focus the light. It looks very
similar to an LED. Be careful not to mix them up. On the lens tip lamp the
polarity makes no difference - this is why the socket is not marked. You
need the lens tip lamp to build a light barrier in combination with the
phototransistor.
The lens tip lamp is designed for a voltage of 9 volts and current of
approx. 0.15 amperes.
