10 exciting solar projects which you can actually use.
Projects featured in this box:
Solar-Powered LED ........................................................................... As long as the sun shines, the LED will light (pag.8)
Flashing Solar LED
Solar-Powered Cricket......................................... ...................... As long as the sun shines, the cricket will chirp (pag.12)
Simple Solar Battery Charger
Solar Battery C harger with ‘Charge’ Indicator
Solar Musical Instrument
IR Remote Control Tester
Solar Garden Light
Solar Motion Detector / Beam Break Detector
Solar-Powered ‘Alarm Armed’ LED
Attention: All projects require direct sunlight or a strong incandescent lightbulb (min 60W). Fluorescent, energ y saving, led
and certain halogen lightsources are not suited or will not give satisfactory results.

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
more electricity. Point the black surface towards the
sun.
Breadboard
Will hold all your experiments. The white lines
show how the holes are electrically connected
with eachother

Resistors

www.vellemanprojects.com
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’.

Diode
Diodes allow the current to flow in only one direction, from
(+) to (–). Current flow in the opposite direction is blocked.
(Vellem an 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. 2V4= 2.4V

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) transistor. A transistor has 3
pins: Base, Emitter and Collector.
Piezo speaker
Microcontroller (µC)
A programmable device which can perform various tasks.
We have pre-programmed it so that it will play musical notes or it
will generate the sound of a cricket. This device is has a polarity.
Watch the position of the notch.
(Velleman part# BC557B)
A piezo speaker converts an electric
signal into sound. Polarity is not
important

Project 1: Solar Powered Led
As long as the sun shines, the led will light...

www.vellemanprojects.com
Required parts: Solar cell, 100 ohm resistor (brown black brown gold), yellow led
or an ge
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. On a sunny
day, the solar cell will generate 3..4
volts. The led only requires 2 volts
to operate. Resistor R1 converts
the excess voltage into (a little)
heat, hereby protecting the led from
damage.
Time to experiment:
What happens when you swap (+) and (-) of the led?
What happens when you replace the 100 ohm resistor with
a 47000 ohm resistor (yellow purple orange gold) ?
