ULN2003A:
The ULN2003A is an array of seven NPN Darlington transistors capable of 500 mA, 50 V output.
ULN2003 is a high voltage and high current Darlington array IC.
It contains seven open collector darlington pairs with common emitters.
Relays
A relay is electro mechanical device that is actuated by an electrical current.
The current flowing in one circuit causes the opening or closing circuit.
which is used for switching between 5 volt circuits and 220/ 120 Volt AC circuits.
Crystal Oscillator
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency.

3. Solar Energy
What is Solar Energy?Solar Energy defination : Energy from the sun.
Electric Energy: the power of the sun to produce electricity through solar cells, that’s known as Photovoltics (PV).
Solar Applications
4 .InverterWhat is inverter ?
Inverter is an electronic device that changes DC to AC.Inverter doesn’t produce any power;The power is provided by the DC source.
