- Page 4 PARTS SUPPLIED WITH THIS KIT: 4V / 30mA solar cell This device will convert sunlight into electricity, which we will use in all projects. More light means (Velleman part# YH-39X35) more electricity. Point the black surface towards the sun. Breadboard Will hold all your experiments.
- Page 5 Ultrabright yellow & red LED Wire jumper Just a piece of bare wire to connect two points in a circuit. Flat side Shortest leg = (-) The yellow & red LED provide a lot of light and require a very low current to operate.

Diode Diodes allow the current to flow in only one direction, from (+) to (–). Current flow in the opposite direction is blocked. (Velleman part# BAT85) A special case: Zener diodes Zener diodes allow the current to flow from (+) to (-), as regular diodes do. If you invert the polarity, they drop a certain voltage, which can be found on the body of the zener diode, e.g. -

A transistor is an amplification device. By means of a small current, Transistors a much larger current is controlled. Transistors come in two flavours, NPN and PNP-types, depending on the polarity. With this C B E kit, you receive a BC557 (PNP) transistor. A transistor has 3 pins: Base, Emitter and Collector. - Page 8 PROJECT 1: SOLAR POWERED LED As long as the sun shines, the led will light...
- Page 9 Required parts: Solar cell, 100 ohm resistor (brown black brown gold), yellow led How it works: A closed circuit is required to make the current flow. Current flows from the (+) of the solar cell trough resistor to the (+) of the led and via the (-) of the led back to the solar cell.
