Resistor
Resistors are used in electrical circuit and are used
in them to regulate the current and the resist the
current flow.
Light Dependent Resistor
(LDR)
LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 1000 000 ohms, but when they are illuminated with light resistance drops dramatically. Transistor
A transistor is a
semiconductor device used to amplify and
switch electronic signals and electrical power. It
is composed of semiconductor material with at
least three terminals for connection to an
external circuit. Variable Resistor (Trim Pot)
A variable resistor is a potentiometer with only
two connecting wires instead of three. However,
although the actual component is the same, it
does a very different job. The pot allows us to
control the potential passed through a circuit. Diode
A diode s are used in electrical circuits and only
allow the electricity to flow only in one direction and
blocks the flow in the other direction.
Switch
This component can come in various forms to
buttons to a thing you slide. It controls the electrical
current in a circuit to stop or let it flow through.
PCB
A printed
circuit board (PCB) is the board base for
physically supporting and wiring the surfacemounted and socketed components in most
electronics. Motor
An electric motor is an electrical machine that
converts electrical energy into mechanical
energy. Popular components not
used in the robobug
Capacitor
This part of a circuit is used to store an electrical
charge and are used in timer circuits. They t can be
used as a timer or to smoothly run a circuit.
Integrated Ciruit (IC) An integrated circuit (IC), sometimes called a
chip or microchip, is a semiconductor wafer on
which thousands or millions of tiny resistors,
capacitors, and transistors are fabricated. An IC
can function as an amplifier, oscillator, timer,
counter, computer memory, or microprocessor
