Getting everything ready
At the beginning of each experiment, you
will find an overview of all the
components that you will need. So start by
looking for all the parts and placing them
in the parts compartment.
The right polarity is important!
Always install the capacitors the right way
around! The assembly drawing shows
exactly how. Also be sure to use the right
capacitance value, 10 µF or 100 µF.
Otherwise, the circuit won't work right.
Insert the LEDs correctly
The LEDs have one long and one short
terminal wire. The short terminal (the
cathode) is indicated with a "C" in the
drawings, and the longer one (the anode)
is indicated with an "A." In addition, the
cathode side of the LED is flattened.
Insert the transistor module
You always have to install the transistor
correctly, too. All of the assembly drawings
are oriented so the "E" (emitter) terminal
is at the bottom, never at the right, left, or
top.
