Connection of the LEDs for the stop and back lights
The two LEDs for the stop and back lights have to be connected in
series, i.e. the anode (+) of the one LED has to be connected to the
cathode (-) of the other LED. Next connect the disconnected anode (+)
with connecting point X8 and the disconnected cathode (-) with
connecting point X3. Additional series resistors are not necessary for
the operation of the LEDs for the stop and back lights.
Connection of the loudspeaker
First connect the basis (B) of the enclosed transistor BC 327 to the
connecting point X6, the emitter (E) to the plus pole of the accumulator
batteries and the collector (C) to the plus pole of the loudspeaker. Next
connect the minus pole of the loudspeaker to the connecting point X1.
If the polarity of the loudspeaker is not given, you may connect it
anyway.
You can reduce the sound volume of the loudspeaker by mounting a
resistor between the collector of the transistor and the plus pole of the
loudspeaker. The resistor should have a value of 10 to 100 . 
Connection of the diodes for the front light
You may connect up to two white LEDs for the front lighting to the
voltage output of the module. These LEDs are not controlled by the
stored software. They light as soon as the module is connected to the
power supply.
Connect the anodes (+) of the LEDs to the soldering point X2 and the
cathodes (-) to the soldering point X3.
Caution: The LEDs for the front lighting must be operated via
series resistors (recommended value: 100 ). Otherwise the
connected LEDs are damaged and the circuit may not work as
intended.
