- Page 4 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 (Velleman part# SDAD102) Resistors Various resistor values are supplied. They serve as current limiters or as voltage dividers. Resistors do not have a polarity.
- Page 5 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 = + (Velleman part# 10J0E) Green...
- Page 6 Push button A push button will conduct current Inside connection when pushed and interrupt the current when released. 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, ...
- Page 7 Transistors A transistor is an amplification device. By means of a small current, a much larger current is controlled. Transistors come in BC547 C B E two flavours, NPN and PNP-types, depending on the polarity. With this kit, you receive a BC557 (PNP) and a BC547 (NPN) transistor.
- Page 8 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) pag.

- Page 13 Required parts: 9V battery*, 1K resistor (brown black red gold), 470K resistor (yellow purple yellow gold), red LED, BC547 transistor, wire jumper. How it works: In this circuit, the small current flowing through your finger will be amplified by the transistor. The base current that runs via your finger and resistor R1, is amplified by transistor T1.

- Page 19 Required parts: 9V battery*, 1K resistor (brown black red gold), 2x 10K resistor (brown black orange gold), red LED, BC547 transistor, phototransistor (TR). How it works: A LED lights up when enough light hits the phototransistor (TR). The phototransistor is light sensi- tive, in dark conditions it has a high resistance, and in light conditions it has a low resistance.
