Basic Electronics Components..
Hi everybody...
In this post I hope to give some basic knowledge
about basic electronics component and I think it will more important for you to
develop your own robot.
Diode
A diode allows
electricity to flow in one direction only and blocks the flow in the opposite
direction. They may be regarded as one-way valves and they are used in various
circuits, usually as a form of protection. There are different types of diode
but their basic functions are the same
Voltage
Regulators
Voltage
regulators use to put constant voltage level in a circuit. Usually regulators having three legs convert varying input voltage
and produce a constant regulated output voltage. The most common part numbers
start with the numbers 78 or 79 and finish with two digits indicating the
output voltage. The number 78 represents positive voltage and 79 negative one.
The 78XX series of voltage regulators are designed for positive input. And the
79XX series is designed for negative input.
Configer 7805
Most
microcontroller IC and digital IC work with 5V voltage level. Therefore always
we have to use 7805 regulator IC and should configure correctly.You can
get sharp knowledge about 7805 and its operation by using its datasheet.
Capacitor
Capacitors are components that are used to store an
electrical charge and are used in timer circuits. A capacitor may be used
with a resistor to produce a timer. Sometimes capacitors are used to smooth
a current in a circuit as they can prevent false triggering of other
components such as relays. When power is supplied to a circuit that includes
a capacitor - the capacitor charges up. When power is turned off the
capacitor discharges its electrical charge slowly
You can get some idea about capacitor by building following circuit
