Basic Electronics for Beginners in 15 Steps
Electrical Electronics Applications
In this lesson, you will learn about basic electronics in 15 steps. It
is easy to get started with basic electronics and by the end of this
lesson, you will be able to read a schematic and build a circuit
using standard electronic components.
There are two types of electrical signals: Alternating Current (AC)
and Direct Current (DC).
Resistors add resistance to a circuit and reduce the flow of
electrical current. They are represented in a circuit diagram as a
pointy squiggle with a value next to it. Different markings on the
resistor represent different values of resistance. Resistors also
come with different wattage ratings. For most low-voltage DC
circuits, 1/4 watt resistors should be suitable. You can tell the
value of each color by looking at a resistor color value chart.
A transistor takes in a small electrical current at its base pin and
amplifies it so that a much larger current can pass between its
collector and emitter pins. The amount of current that passes
between these two pins is proportional to the voltage being
applied at the base pin.
An integrated circuit is an entire specialized circuit that has been
miniaturized and fit onto one small chip with each pin of the chip
connecting to a point within the circuit.
Potentiometers: Potentiometers are variable resistors that have
a knob or slider to change resistance in a circuit.
LEDs: LEDs (Light Emitting Diodes) are special diodes that light
up when electricity passes through them. They create a voltage
drop but don't add resistance; however, to prevent circuit
shorting, a resistor in series is essential.
Breadboards: Breadboards are circuit boards with split holes
arranged into electrically continuous rows, providing a quick
method for building circuits without soldering or twisting wires
