Breadboard
With a breadboard simple electronic circuits
can be set up and changed very quickly.
Our small breadboard has eleven rows of
five pins each connected internally. The
outer two rows are used for the power
supply (+/-). The rest are labeled with the
numbers 1 to 9.
The fifth row in the middle is concealed at
varikabi with the black cable tie and is not
needed.
Resistor
The resistor limits the current of the two
LEDs. The colored rings indicate the value of
the ohmic resistance, which in our case is
150 Ω (ohms).
Bend the connecting wires of the resistor at
a distance of 10 mm and shorten them to a
length of approx. 15 mm. Then put the
resistor in the center of the breadboard.
