YEAH!A REAL DT POST!
YES!AND YES!:Dtime to work!my dear me!
hahahahas,okies
today i am going to talk about....
electrical component!
YEAH!
Circuit symbols are used in circuit diagrams which show how a circuit is connected together electrically. They are used when designing and testing circuits, and for understanding how they work. And just imaging drawing the real batteries and switch out,that will waste alot of time,is't it? So,to save time,there is symbol for us to follow.
batteries
Batteries come in all shapes and sizes. They store electrical charge and as we all know when they are put into an electronic device such as a portable radio, they provide the power.
buzzer
A buzzer or beeper is a signalling device, usually electronic, typically used in automobiles, household appliances such as a microwave oven, or game shows.
motor
An electric motor uses electrical energy to produce mechanical energy. The reverse process, that of using mechanical energy to produce electrical energy, is accomplished by a generator or dynamo. Traction motors used on locomotives and some electric and hybrid automobiles often perform both tasks if the vehicle is equipped with dynamic brakes. Electric motors are found in household appliances such as fans, refrigerators, washing machines, pool pumps, floor vacuums, and fan-forced ovens.
resistor
A resistor is a two-terminal electronic component that opposes an electric current by producing a voltage drop between its terminals in proportion to the current, that is, in accordance with Ohm's law: V = IR. The electrical resistance R is equal to the voltage drop V across the resistor divided by the current I through the resistor. Resistors are used as part of electrical networks and electronic circuits.
Light bulb
The incandescent light bulb, incandescent lamp or incandescent light globe is a source of artificial light that works by incandescence, (a general term for heat-driven light emissions which includes the simple case of black body radiation). An electric current passes through a thin filament, heating it until it produces light. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation.
wire
A wire is a single, usually cylindrical, elongated string of drawn metal. Wires are used to bear mechanical loads and to carry electricity and telecommunications signals. Standard sizes are determined by various wire gauges.
LED
A LED is usually a small area light source, often with optics added to the chip to shape its radiation pattern and assist in reflection.LEDs are often used as small indicator lights on electronic devices and increasingly in higher power applications such as flashlights and area lighting. The color of the emitted light depends on the composition and condition of the semiconducting material used, and can be infrared, visible, or ultraviolet. LEDs can also be used as a regular household light source. Besides lighting, interesting applications include sterilization of water and disinfection of devices.
Pictures will be on next post and hope you enjoy this imformation!

HEY HEY!I am updating on my dt blog now!
okay,
i have started my dear journal and
i have done
1.problem situation(3)
2.Design brief
3.Analysis
4.research
-function
-aesthetic
-ergonmics
-material
-innovation
-environment
market research
mechanism
electrical components
yeahs andthats what i have done
hope to update more about designs and technology
update soon!:DDDD
