e) Diode
Angle the pins of the silicon diode with a small set of flat pliers or another suitable tool. When soldering them in, observe the polarity of the diode.
The white ring on the diode indicates the cathode (minus, "-").
The white ring on the diode indicates the cathode (minus, "-").
D4 = 1N4001
f) LEDs and IR LEDs
Make sure that the polarity is correct when installing the LEDs. You can identify the cathode of the LED/IR diodes by the slightly flattened side of
the plastic housing. Another detection criterion is that the pins of the anode ("+") are longer than those of the cathode ("-").

You should solder in the red 5mm-LED (part D1) at the end once the wheels are mounted and the two ping-pong ball halves
are correctly attached. The red 5mm-LED should only have a distance of approx. 5mm to the floor, otherwise the illumination
for the photo transistors is not sufficient!

for the photo transistors is not sufficient!
D1 = 5mm LED "red"
D5 = 3mm low current LED "green"
D12, D13, D14, D15 = 3mm low current LED "red"
Contrary to the standard LEDs and IR LEDs, the housing of the IR-LED for the two wheel encoders is flat and square. With respect to the polarity,
the same applies as for the red/green LEDs: the longer pins indicate the anode ("+"). The small catch on the one side must point towards the
gearwheel, see imprint on the circuit board.

Do not mix up the two IR-LEDs with the two photo transistors (see next page)! The IR-LEDs have a slightly pink housing, the photo
transistors have a transparent housing. If you place the 4 components on a white sheet of paper, the difference is easily visible (see
image below).
