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.
