Parts supplied with this kit:
Breadboard
The breadboard will hold all your
experiments. The white lines show how the
holes are electrically connected wit h
eachother
Resistors
R1
100
(Velleman part# SDAD102)
Various resistor values are supplied. They serve as
current limi ters or as voltage div iders. 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)

Capacitors
A capacitor is almost lik e a small battery, it can be charged
using a power supply. Mostly used to stabilise or to filt er out
unwanted voltages. The unit is Farad: practi c al v alues are
in µF, nF or pF. The supplied capacitor is an Electrolytic
capacitor of 10µF and has a polarity, the long lead = +
(Velleman part# 10J0E)
Green & red LED
How to bend the leads:
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 = + !

Push button
A push button will conduc t current
when pushed and interr upt the
current when released.

Buzzer
pag. 6
Inside connection
The supplied button
has 4 connections, but
only 2 are used.
2 are interconnected.
A buzzer produce a signalling sound to alert
for a dangerous situation, timer confi rmation,
a button is pressed, .. . T he pitch of the buzzer
can't be changed because the frequency of
the oscillat or is fixed.

Transistors

NPN
A transistor is an amplification device. By means of a small
current, a muc h larger current is contr olled. Transistors come i n
C
two flavours, NPN and PNP-types, depending on the polarity.
With this kit, you receive a BC557 (PNP) and a BC547 (NPN)
transistor. A tr ansistor has 3 pins: Base, Emitt er and Collector.

A Light Dependent Resistor behaves
like a resistor. T he resistance v arious
on the amount of light falling on the
device, it decreases with increasing
light intensity.

Flatcable
8x
Includi ng in this box you can find a mult i-cor e cable. The
wires must be separated from each other before use.
This can be done using a wire-c utter or pair of scissors.
Use the separate wir es to c onnec t component s (indicated
in the drawing by a thick black line)
