FUTURITY AUDITORIUM
A Comparator is a device that compares two voltages or currents and switches its output to indicate which is larger.
An operational amplifier (op-amp) has a well balanced difference input and a very high gain.
The comparator output satisfies the following rules:
When V+ is larger than V- the output bit is 1.
When V+ is smaller than V- the output bit is 0
FND DISPLAY
A seven-segment display, or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot-matrix displays.
MICRO CONTROLLER
A Microcontroller is designed for a very specific task -- to control a particular system.
MICROCONTROLLER
A single chip that contains the processor (the CPU), non-volatile memory for the program (ROM or flash), volatile memory for input and output (RAM), a clock and an I/O control unit.
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 very precise frequency
PHOTO DIODE
A photodiode consists of an active p-n junction which is operated in reverse bias. When light falls on the junction, a reverse current flows which is proportional to the illuminance. The linear response to light makes it an element in useful photodetectors for some applications
LIGHT EMITTING DIODE(LED)
Led are used as indicator lamps in many devices and are increasingly used for other lighting.
OPTOCOUPLER
An Opto-Coupler is a device that consists of an LED light bulb and photodiode.
An optocoupler, is "an electronic device designed to transfer electrical signals by utilizing light waves to provide coupling with electrical isolation between its input and output
