Parts supplied with this kit:
Breadboard
The breadboard will hold all your experiments. The white lines show how the holes are electrically connected with eachother
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)

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 = +

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 conduct current when pushed and interrupt the current when released.
Inside connection
The supplied button has 4 connections, but only 2 are used.
2 are interconnected.
(Velleman part# D6)
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.

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.

LDR (Light Dependent Resistor)
A Light Dependent Resistor behaves like a resistor. The resistance various on the amount of light falling on the device, it decreases with increasing light intensity.

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)
