Resistors
Various resistor values are supplied. They serve as
current limiters or as voltage dividers. Resistors do not
have a polarity. Resistors values are indicated by
means of coloured rings. The unit of resistance is called
’Ohm’. ( see colour code table in the package)
Parts supplied with this kit:
The breadboard will hold all your
experiments. The white lines show how the
holes are electrically connected with
eachother (Velleman part# SDAD102)

Capacitors
A capacitor is almost like a small battery, it can be charged
using a power supply. Mostly used to stabilise or to filter out
unwanted voltages. The unit is Farad: practical values are
in µF, nF or pF. The supplied capacitor is an Electrolytic
capacitor of 10µF and has a polarity, the long lead = +

Green & red LED
A LED is a Light Emitting Diode, it
can emit light using a small current
(max 20mA with a 1.8V drop).
Watch the polarity, long lead = + !

Buzzer
A buzzer produce a signalling sound to alert
for a dangerous situation, timer confirmation,
a button is pressed, ... The pitch of the buzzer
can't be changed because the frequency of
the oscillator is fixed. (Velleman part# SV3)
Push button
A push button will conduct current
when pushed and interrupt the
current when released.
(Velleman part# D6)
Inside connection
The supplied button
has 4 connections, but
only 2 are used.
2 are interconnected.

Transistors
A transistor is an amplification device. By means of a small
current, a much larger current is controlled. Transistors come in
two flavours, NPN and PNP-types, depending on the polarity.
With this kit, you receive a BC557 (PNP) and a BC547 (NPN)
transistor. A transistor has 3 pins: Base, Emitter and Collector.

A phototransistor is a transistor
that conducts current when the
photocell inside it is sufficiently
exposed to light. You can use it
as a light switch in electrical
circuits. Velleman part# SGPT5053C )

Flatcable
Including in this box you can find a multi-core cable. The
wires must be separated from each other before use.
This can be done using a wire-cutter or pair of scissors.
Use the separate wires to connect components (indicated
in the drawing by a thick black line) Velleman part# FC8)
