Let's learn something about the
components you've got!
1. Circuit board
The black head-shaped thingy you've gotten in your kit is called a circuit board.
Professionals call this a printed circuit board or PCB.
A PCB is a laminated sandwich structure of conductive and insulating layers.

What does it do?
Your circuit board has two functions:
● It holds all the electronic components in place.
● It provides electrical connections between the electronic components.
Because of the circuit board, all electronic components can work together as a team.
What are those tiny lines on my circuit board?
They allow electrical charges to flow between components. This way, electronic
components are powered, and they can do clever stuff using electricity.
What is my circuit board made of?
Circuit boards are usually made out of fiberglass-reinforced epoxy-laminated sheets.

These are also referred to as “FR4” sheets.
The FR4 sheets are used as the insulating non-conductive material, and copper is used as
a conductive material.
If material is conductive, it conducts electricity; electrical charge can flow through that
material easily.
FR4 and copper are both sandwiched together in thin sheets, and that’s how you get a
circuit board.
Where are PCBs used?
They’re used everywhere!
In your phone, in your laptop, in your refrigerator, air conditioner. Basically, every electronic
device you use has a unique printed circuit board that makes it work.
Did you know?
A PCB is one of the most important inventions of the last 100 years.
Space travel wouldn’t be possible without them.
PCBs were invented by Paul Eisler.
He invented it in the 1930s, but the predecessors of modern-day PCBs have been around
since the age of gramophones and vacuum tube radios, just in a somewhat different form.

2. Resistors
Resistors are the most basic electronic components found in almost every electronic device.
They fall in the category of passive electronic components.
Passive electronic components do not generate electrical power and do not need electrical
power to work.
They just modify the flow of electrical energy in their own unique way.
Resistors that you have gotten in your package have a cylindrical shape and two tiny metal
legs.
We call these legs "component leads".

Resistance
Resistors have a property of resistance - they lower the amount of electrical energy flowing
through the circuit.
They “resist” the flow of electrical energy.
The unit of resistance is called ohm and it was named after German physicist Georg Simon
Ohm.
Resistors are used for tasks such as adjusting the flow of electricity through an electronic
circuit.
The exact value of a resistor is measured with a device called an ohmmeter.
Can we compare it to something we see in everyday life?
If we make an analogy to water flowing through pipes, the resistor is a thin pipe that
reduces the water flow.

Scientists and engineers have come up with different symbols for each and every electronic
component.
This is an electronic symbol for a resistor:
This is Georg Simon Ohm:

3. Switch
The switch you got in your kit helps you turn the device on and off. You can easily do so
with one simple push.
A switch controls the flow of power to an electric device - in other words, it connects and
disconnects an electrical circuit.
Switches are used in almost every electronic device. They are found in your mobile phone,
computer, air conditioner, etc.
Historical fun fact:
An electrical switch was invented in 1884 by John Henry Holmes, who used it for turning
lights on and off.
4. Capacitor
A capacitor is a component that has the ability to store energy, much like a small

rechargeable battery.
This is an electronic symbol of a capacitor:

A capacitor can absorb energy from a circuit and store it temporarily.
Later on, this stored energy can be released back to the electronic circuit.
We can measure the ability of a capacitor to store electrical energy.
We call this property - capacitance.
The unit of capacitance is called Farad (we use the letter F as a short for Farads).
This unit was named after physicist Michael Faraday.
Historical fun facts:
Capacitors were discovered by Pieter van Musschenbroek a looong time ago - in 1746.
The first capacitor was a glass jar wrapped inside and out by a thin metal foil.
5. Transistor

The transistor is an electronic component that can be used as part of an amplifier or as a
switch.
It is made of semiconductor material.
Transistors have 3 terminals: the emitter, the collector, and the base. When the emitter is
connected to the negative terminal of the battery and the collector to the positive terminal,
no electricity will flow in the circuit.
This is what a transistor looks like:
6. Red LEDs
These electronic components will make your CAPACITRON’s eyes light up.
LED stands for light-emitting diodes.
LEDs convert electrical energy into visible light.
This is an electronic symbol for a light-emitting diode:

Watch out - LEDs are polarized!
Light-emitting diodes (LEDs) are polarized.
This means that they only allow current to flow in one direction.
Because of this, you need to pay attention to how you are going to place your LED in the
electronic circuit.
The tiny metal legs of every LED are not the same length.
They mark polarity!
The positive leg is longer (we call this one the anode), and the shorter one is negative (this
one has a funny name - cathode).
If you put the LED in the wrong way, it won't light up because the electrical energy will not
be able to flow through it.

Electrical energy flows from the anode to the cathode and not in the opposite direction.
Resistors and LEDs make a great team!
LEDs can be damaged if they receive too much energy.
Oh no! The coin cell battery supplied with your CAPACITRON is too much for the poor little
LEDs.
But don't worry, we sent resistors to the rescue!
Resistors will limit the amount of electrical energy flowing through the circuit and save your
LEDs from getting damaged.

Historical fun facts:
A Russian inventor Oleg Vladimirovich Losev made the first LED in 1927.

Did you know?
LED lightbulbs are the most efficient type of lightbulbs.
Unlike “regular” “old” bulbs (we call these incandescent lightbulbs), which release 90% of
their energy as heat, LEDs use energy far more efficiently with very little wasted heat.
Meet the tools!
Soldering iron
For Artemis' assembly, any entry-level soldering iron will suffice.
Although, if you plan to dive into the world of DIY projects, you should consider getting a
more expensive one with more features.
