Rolling display using Matrix LEDs

Abstract:
This project can be used for Advertising or for providing information at various places like shops, government offices, hospitals, railway stations. The Rolling display is prepared using 5 X 7 Matrix LEDs which means LEDs are arranged in a pattern consisting of 5 columns and 7 rows. A matrix of 5 X 7 LEDs contribute to a single character. Here we have used 6 characters which means 6 matrices. The actual physical diamension of single matrix is 10 cm by 8 cm, so diamension of complete displa ....etc

digital dice using 8051 microcontroller at89c51

It is a project that builds microcontroller programming interest in new student and hobbies. This project is a very simple one that can easily be built by new students. It uses 7 LEDs, 8051 microcontroller and an optional 5V power supply regulator part. It s algorithm is also very simple.
1) Initially microcontroller displays 1 on LEDs display just like in real dice.
2) Then in main while loop it waits for switch attached to pin 0 of port 1 to be pressed.
3) Until switch remains pressed it gener ....etc

hey guys, looking for some code to display numbers 1 to 6 on 7 segment display. Thinking of polling the one of the pins connected to the switch and using an auto reload timer that counts from 249 to 249 as 1 to 6. Know what i want to do but need some help with the code?? thanks ....etc

final report file of digital dice using ic 555 in pdf

Playing with dice is an age old game. We all love to play with it too. Playing with dice needs us to pick up a dice and make sure that it is unbiased. Making a block as a dice and cutting it clearly to make sure that it is unbiased is all an old story. The dice becomes biased if the shape is not cut well. Also, the dice can become biased due to deformations. If it is a wooden die, it can deform due to dampness in the atmosphere or due to mechanical stress. To solve all these problems which ....etc

General Description
The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V. The circuit contains its own adjustable reference and accurate 10-step voltage divider. The low-bias-current input buffer accepts signals down to ....etc
