It talk to u about LED display. its going to be 6000 words report,
Need to use multisim and proteus?
have build the circuit diagram on multisim and proteus, also have the program written, all u need to do its simulate it and take the necessary results.
An Led Dot Matrix Display Board is a programmable board used mainly for the purpose of advert. This technology makes use of individual leds to form an LED matrix screen of either 5X7, 5X8 or 8X8 matrix screen. This led matrix is multiplexed (i.e. expanded by making use of some special digital decoder ICs (integrated circuit chips). These digital decoder chips are linked to an on-chip microcomputer chip called microcontroller. This microcontroller controls the output of these digital ICs with respect to the written code (i.e. the program running the controller) in order for the written advert to be displayed on the LEDs matrix screen.

A three-phase four wire 480Y /277 volt service is sized to carry 375 amperes per phase. Sketch a metering circuit,including instrument transformers, that provides line-to-neutral voltage, phase current, and kilowatt-hour metering.
a circuit consists of three elements in series. a source delivers 90 watts and one of the passive elements absorbs 20 watts. how much power does the third element absorb.
build a circuit for a parking deck where a binary counter counts up when a car comes in and down when one leaves. There can only be a maximum of 40 cars in the parking deck before an LED turns on to notify the parking deck is full.
An infinite line of charge sits on the z axis in free space. The linear charge density is p = 1C/m. What is the potential difference at point (2,pi/2,4) with respect to point (5,0,1) assuming both points are in cylindrical coordinates.
