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. (Velleman part# YH-39X35) Breadboard Will hold all your experiments.
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. Watch the polarity ! (Velleman part# L-5YAC & L-7104LID) 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.
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. 2V4= 2.4V Battery holder (Velleman part# ZA2V4) Holder for two AAA rechargeable batteries.
Transistors E B C C B E 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. (Velleman part# BC557B) Piezo speaker A piezo speaker converts an electric signal into sound.
PROJECT 1: SOLAR POWERED LED As long as the sun shines, the led will light...
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. 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.
PROJECT 2: SOLAR FLASHING LED Solar powered attention grabber µC Jumper wire 10
Required parts: Solar cell, 100 ohm resistor (brown black brown gold), yellow led, microcontroller (µC), wire jumper. IC1 PIC10 F20 0-I/PG VDD 2 How it works: The controller requires 2-5V to operate. This voltage is supplied by the solar panel. The microcontroller is pre-programmed with software that turns the output on and off in a loop. The signal is output via pin 4. When the output is on, current flows via the led and the resistor, hereby causing the led to light.

The microcontroller is pre-programmed with software that generates a realistic cricket chirp.
PROJECT 4: SIMPLE SOLAR BATTERY CHARGER Insert two AAA 1.
Required parts: Solar cell, BAT85 diode, battery holder for two AAA batteries, two AAA 1.2V rechargeable batteries. How it works: As long as the solar cell is exposed to light, a current will flow from the solar cell via the diode trough the batteries and back to the solar cell. The charge current depends on the amount of light that reaches the solar cell. Max. current with the supplied cell is 30mA. A diode prevents discharge of the batteries trough the solar cell (e.g.
PROJECT 5: SOLAR BATTERY CHARGER WITH ‘CHARGE’-INDICATOR A led turns on when the batteries are charging... Insert two AAA 1.
Required parts: Solar cell, BC557 transistor, 4K7 resistor (yellow, purple, red, gold), yellow led, battery holder for two AAA batteries, How it works: When the sun shines, a current flows from the (+) of the solar cell via the Emitter/Base of the transistor trough the batteries and back to the solar cell. This is the Base current, indicated with the dotted line. In our example, the Base current will also charge our batteries.
PROJECT 6: SOLAR MUSICAL INSTRUMENT More light = higher note Wire Jumper wire 4K7 4K7 µC PIC 470 18

Once it receives 47 0 R1 2VDC it starts running its internal 4K7 program.
PROJECT 7: IR REMOTE CONTROL TESTER ‘Listen’ to your IR remote PI +/- 5cm 20
How it works: Solar cells are sensitive to infrared light. When hit by infrared light, they generate a voltage, like they do with sunlight. IR remote controls generate a beam of infrared light when they are operated. This beam of light is turned on and off very fast by the internal electronics of the remote control. The pattern generated by the on-off transitions is different for each button of the remote. This allows the receiver to recognise each individual button.
PROJECT 8: SOLAR GARDEN LIGHT Led turns on at dusk and turns off at dawn, fully automatic 470 4K7 Jumper wire Insert two AAA 1.

Once the controller receives 2VDC it starts running its internal program.
PROJECT 10: SOLAR POWERED ‘ALARM ARMED’-LED Charges during the day, scares burglars at night Insert two AAA 1.
Required parts: Solar cell, microcontroller (µC), 4K7 resistor (yellow, purple, red, gold), 100 ohm resistor, (brown, black, brown, gold), BAT85 diode, BC557 transistor, battery How it works: When the sun shines, the voltage generated by the solar cell will be higher than the voltage of the batteries, so a current will flow from the solar cell to the batteries. This current will charge the batteries. The BAT85 diode prevents discharging of the batteries trough the solar cell in low light conditions.
